Abstract: "Video games that customize to a player's experience level and abilities have the potential to allow a broader range of players to become engaged and maintain interest as they progress in experience level. A game that uniquely customizes the player's experience could attract additional demographics to gaming, which will result in a distinct edge in marketability and potential revenue. This thesis examines a subsection of adaptive gaming systems from the perspective of identifying game factors that alter the level of difficulty. Our focus is to provide a solution useful to both research and commercial gaming communities by developing a system that simulates results offline yet can be integrated into online play. While online performance is the main goal of an adaptive system, the offline simulation provides several benefits. Offline simulation allows the elimination of insignificant factors from inclusion in the training and evolution phase of machine learning algorithms. In addition it provides commercial games with a useful tool or method for performing game balancing and level tuning. To test our approach we designed a test-bed version of the game Pac-Man. The experimental testbed alters environment variables to evaluate their effect on a set of selected response variables. Observing the results of several response variables provides the potential to represent multiple player states, though our focus is on controlling the difficulty for a player. The testbed will simulate the actions of both Pac-Man and the ghosts over a variety of different settings and strategies. The evaluation of a factor's significance and its effect size are calculated using a factorial analysis approach. This method allows the identification of factors relevant to both individual strategies, and the set of all player strategies. Finally, as a proof of concept for both the online and adaptation prospects of this method, we developed a prototype adaptive system. Utilizing the releva

From the abstract: "Our goal is to create a better understanding on how to design encounters that affect interest levels in linear FPS games. Specifically, how exactly a player's interest levels can be raised intentionally. To accomplish this, we developed a method for measuring and comparing player interest levels based on electroencephalogram (EEG) data measured using a "Neurosky Mindset" unit, which is a commercially available EEG device. We measured player EEG data for the first 4 levels of the FPS game "Call of Duty: Modern Warfare 2" and calculated player interest levels for the entire length of gameplay. By referring to recorded gameplay videos, we were able to associate each increase in interest levels for each player to a specific point in game. From this data, we found and isolated points in each level where most players showed a rise in interest levels, and discovered that certain patterns existed between these situations. These findings led to another study where we further analyzed these situations and found out what factors caused most players to show a rise in interest levels. We were able to divide these factors into 6 different categories called Triggers: "Anticipation", "Concentration", "Surprise", "Frustration", "Overwhelm" and "Fear". As these triggers represent mutually exclusive elements that affect a player's interest levels, we found that in most situations where many test subjects showed a rise in interest levels, more than one trigger is present, a phenomenon we call Stacking. While our study is still ongoing, we believe that by using these triggers as guidelines, game designers will be able to intentionally plan and control the player's interest level for FPS games with a certain level of guarantee"

"Abstract: Digital games have the potential to create active and engaging environments for learning, supporting problem-solving, communication and group activities, as well as providing a forum for practice and learning through failure. The use of game techniques such as gradually increasing levels of difficulty and contextual feedback support learning, and they can motivate users, using challenges and rewards, competition and mystery. Above all, computer games provide safe spaces in which learners can play, explore, experiment, and have fun. However, finding appropriate games for specific educational contexts is often problematic. Commercial entertainment games are designed for enjoyment, and may not map closely to desired learning outcomes, and the majority of educators do not have the time or specialist expertise to create their own games. Computer games are expensive to purchase or produce, and learners, particularly busy adult learners, need to be convinced of their effectiveness. So while there are many theoretical benefits to the use of computer games for learning, it given the increasing economic constraints in education, their use may simply not be practical. This paper presents three alternative ways in which the theory and practice of computer games can be applied to education, without the expense. First, the option of developing simple and cost-effective games with low technical specifications, such as alternate reality games, or using virtual worlds or one of the growing number of accessible game-builder toolkits to create educational games, will be explored. Second, learning from games rather than with them is discussed, examining game techniques that naturally enhance learning, and embedding those elements in traditional teaching practices. Third, the paper presents the option of giving learners agency as game creators rather than simply players, so that it becomes the process, not the product, which facilitates learning. The advantages and drawbacks

"This project involves developing an action-platformer game for the Flash platform. The user controls a character who must progress through levels, while avoiding obstacles, collecting items and fighting many types of enemies. Role-playing game elements such as equipment and upgrades support user customization and varied battle strategies. Developing a successful Flash game involves several factors. Flash games must be simple to get into, yet rewarding to play in both short and long sessions. Flash games must be accessible to a wide audience; both in terms of user preferences and technical limitations. Finally, Flash games must offer something unique to stand out from the crowd, in a market where hundreds of free games are published every month. This report covers the research, design and implementation done to achieve these requirements, in terms of game mechanics, interface, level design, visual design, accessibility options, and replay value. Technical challenges include building, testing and optimizing a game engine and interface from scratch, balancing the game mechanics and difficulty, and structuring the whole development process in a way that enables easy creation of new content. In addition to game design and development, this project also deals with the business aspects of developing online games; how games generate revenue, how they are marketed and distributed, and developing trends in the consumer market. Project success in different areas has been evaluated through usability studies, user ratings and reviews, and vast quantities of usage and distribution statistics. Overall, the project has been a success in terms of user reception and generated revenue, and the final section of this report includes plans for a second game, utilizing and building upon the same game engine and mechanics."

Abstract: "This paper discusses how to use design patterns in procedural level generation, with particular reference to the classic console game Super Mario Bros. In a previous paper, we analyzed the levels in this game to nd a set of recurring level design patterns, and discussed an implementation where levels were produced from concatenation of these patterns. In this paper, we instead propose using patterns as design objectives. An implementation of this based on evolutionary computation is presented. In this implementation, levels are represented as a set of vertical slices from the original game, and the tness function count the number of patterns found. Qualitative analysis of generated levels is performed in order to identify strengths and challenges of this method"

"This dissertation presents the use of procedural content generation to create expressive design tools: content generators that are accessible to designers, supporting the creation of new kinds of design tools and enabling the exploration of a new genre of game involving the deep integration of procedural content generation into game mechanics and aesthetics. The first of these tools is Tanagra, the first ever AI-assisted level design tool that supports a designer creating levels for 2D platforming games. Tanagra guarantees that levels created in the tool are playable, and provides the designer with the ability to modify generated levels and directly control level pacing. The second tool is Launchpad, which supports a designer controlling both component and pacing features of generated levels; its companion game Endless Web uses the generator to create an infinite world for players to explore and alter through their choices. Endless Web is one of a handful of games in a new genre enabled by content generation: PCG-based games. Finally, this dissertation presents a novel method for understanding, visualizing, and comparing a generator's expressive range, thus allowing designers to understand the implications of decisions they will make during the design process."

From the abstract: "Traditionally, the tasks associated with game AI revolved around non player character (NPC) behavior at dierent levels of control, varying from navigation and pathnding to decision making. Commercial-standard games developed over the last 15 years and current game productions, however, suggest that the traditional challenges of game AI have been well addressed via the use of sophisticated AI approaches, not necessarily following or inspired by advances in academic practices. The marginal penetration of traditional academic game AI methods in industrial productions has been mainly due to the lack of constructive communication between academia and industry in the early days of academic game AI, and the inability of academic game AI to propose methods that would signicantly advance existing development processes or provide scalable solutions to real world problems. Recently, however, there has been a shift of research focus as the current plethora of AI uses in games is breaking the non-player character AI tradition. A number of those alternative AI uses have already shown a signicant potential for the design of better games. This paper presents four key game AI research areas that are currently reshaping the research roadmap in the game AI eld and evidently put the game AI term under a new perspective. These game AI agship research areas include the computational modeling of player experience, the procedural generation of content, the mining of player data on massive-scale and the alternative AI research foci for enhancing NPC capabilities."

Abstract: "Player coordination is a key element in many multi-player real-time digital games and cooperative real-time multi-player modes are now common in many digital-game genres. Coordination is an important part of the design of these games for several reasons: coordination can change the game balance and the level of difficulty as different types and degrees of coordination can make the game easier or more difficult; coordination is an important part of 'playing like a team' which affects the quality of play; and coordination as a shared activity is a key to sociality that can add to the sociability of the game. Being able to exercise control over the design of these coordination requirements is an important part of developing successful games. However, it is currently difficult to understand, describe, analyze or design coordination requirements in game situations, because current frameworks and theories do not mesh with the realities of video game design. I developed a new framework (called PLATO) that can help game designers to understand, describe, design and manipulate coordination episodes. The framework deals with five atomic aspects of coordinated activity: Players, Locations, Actions, Time, and Objects. PLATO provides a vocabulary, methodology and diagram notation for describing and analyzing coordination. I demonstrate the framework's utility by describing coordination situations from existing games, and by showing how PLATO can be used to understand and redesign coordination requirements."

Abstract: "This paper describes the design and evaluation of Zoo U, a novel computer game to assess children's social skills development. Zoo U is an innovative product that combines theory-driven content and customized game mechanics. The game-like play creates the opportunity for stealth assessment, in which dynamic evidence of social skills is collected in real time and players' choices during gameplay provide the needed data. To ensure the development of an engaging and valid game, we utilized an iterative datadriven validation process in which the game was created, tested, revised based on student performance and feedback, and retested until game play was statistically matched to independent ratings of social skills. We first investigated whether the data collected through extensive logging of student actions provided information that could be used to improve the assessment. We found that detailed game logs of socially relevant player behavior combined with external measures of player social skills provided an efficient vector to incrementally improve the accuracy of the embedded assessments. Next, we investigated whether the game performance correlated with teachers' assessments of students' social skills competencies. An evaluation of the final game showed (a) significant correlations between in-game social skills assessments and independently obtained standard psychological assessments of the same students and (b) high levels of engagement and likeability for students. These findings support the use of the interactive and engaging computer game format for the stealth assessment of children's social skills. The created innovative design methodologies should prove useful in the design and improvement of computer games in education."

Abstract: "As the video game industry grows, both developers and cre- ative authors are seeking new ways to convert story content into scripting code, which is often a difficult process dur- ing game creation. ScriptEase II provides a solution to this common bottleneck in the games design process. Although the goals are similar to the goals of ScriptEase, ScriptEase II is able to generate code for any game engine with a provided translator. It utilizes high-level game design patterns such as cause-effect and quest patterns which can be abstracted between most games. In addition, ScriptEase II further en- hances the use of these patterns with a simple drag-and-drop interface. The generality of the code generation has been tested using two different game engines, and it can be used to further test the benefits of using high-level game design patterns in content creation."

From the abstract: "In this paper we tackle automating level design. We describe a general graph-based representation for game levels and present a preliminary system that leverages this representation. Our system automatically explores existing levels of a 2D platform game using the rapidlyexploring random tree (RRT) algorithm and constructs a compact graph representation from this exploration. Our system can also modify a graph representation onthe- fly to reflect user-directed changes to the existing level structure. This work constitutes an initial step toward the larger goal of automating level design in a general way."

Abstract: "A recent trend within computational intelligence and games research is to investigate how to affect video game players' in-game experience by designing and/or modifying aspects of game content. Analysing the relationship between game content, player behaviour and self-reported affective states constitutes an important step towards understanding game experience and constructing effective game adaptation mechanisms. This papers reports on further refinement of a method to understand this relationship by analysing data collected from players, building models that predict player experience and analysing what features of game and player data predict player affect best. We analyse data from players playing 780 pairs of short game sessions of the platform game Super Mario Bros, investigate the impact of the session size and what part of the level that has the major affect on player experience. Several types of features are explored, including item frequencies and patterns extracted through frequent sequence mining."

Abstract: "Procedural content generation (PCG) is concerned with automatically generating game content, such as levels, rules, textures and items. But could the content generator itself be seen as content, and thus generated automatically? This would be very useful if one wanted to avoid writing a content generator for a new game, or if one wanted to create a content generator that generates an arbitrary amount of content with a particular style or theme. In this paper, we present a procedural procedural level generator generator for Super Mario Bros. It is an interactive evolutionary algorithm that evolves agentbased level generators. The human user makes the aesthetic judgment on what generators to prefer, based on several views of the generated levels including a possibility to play them, and a simulation-based estimate of the playability of the levels. We investigate the characteristics of the generated levels, and to what extent there is similarity or dissimilarity between levels and between generators."

Abstract: Video games are no longer a means of simple entertainment that serve as a form of escapism. They are perceived not simply as free time distractions, but as logic of engagement and platforms of creative thinking. Furthermore, online video games have taken the idea of interaction to a level no any other media has ever achieved. Online video games known as virtual world or MMO (massively multiplayer online) are a mega interaction platform that attract millions of players across the globe. They are the ultimate goal that all architects have ever dreamed of, i.e. to create an interactive space that satis es the needs of users. This thesis research will tend to examine a variety of video games from 3 perspectives: space, structure and interactivity, with a view to understanding and exploring the behaviour of players in video games, as known as, virtual stages. In recognizing and articulating such behaviour, followed by exploring the relationship between architects, users and spaces, the interpretation of architectural languages can then be translated into physical spatial form. This research then questions the possibilities of promoting the gaming industry in South Africa. In the current digital era, the IT (information and technology) industry is a main stream profession that helps with the growth of a country as a whole. The role of the gaming industry therefore cannot be ignored in this instance. The gaming industry is a rapid growing profession that comprises a lot of speci c professionals. SA does not offer nor focus on the video game eld and as a result, we are experiencing a shortage of professionals in this eld. This thesis proposes a facility to facilitate current and future game industry related professionals, on the same time, providing a playful environment that integrates the building and local context, allowing deeper engagement for those who haven t been exposed to the real meaning behind video games.

Abstract: "We introduce Mechanic Miner, an evolutionary system for discovering simple two-state game mechanics for puzzle platform games. We demonstrate how a re ection-driven generation technique can use a simulation of gameplay to select good mechanics, and how the simulation- driven process can be inverted to produce challenging levels specic to a generated mechanic. We give examples of levels and mechanics generated by the system, summarise a small pilot study conducted with example levels and mechanics, and point to further applications of the technique, including applications to automated game design."

"This paper describes the creation of the game Endless Web, a 2D platforming game in which the player's actions determine the ongoing creation of the world she is exploring. Endless Web is an example of a PCG-based game: it uses procedural content generation (PCG) as a mechanic, and its PCG system, Launchpad, greatly influenced the aesthetics of the game. All of the player's strategies for the game revolve around the use of procedural content generation. Many design challenges were encountered in the design and creation of Endless Web, for both the game and modifications that had to be made to Launchpad. These challenges arise largely from a loss of fine-grained control over the player's experience; instead of being able to carefully craft each element the player can interact with, the designer must instead craft algorithms to produce a range of content the player might experience. In this paper we provide a definition of PCG-based game design and describe the challenges faced in creating a PCG-based game. We offer our solutions, which impacted both the game and the underlying level generator, and identify issues which may be particularly important as this area matures."

Abstract: "Design techniques can have an important effect on how video games teach and players learn. The ability to harness these techniques in the design of educational video game can impact the motivation and engagement of playing and learning by creating more options for players to connect with game content as well as to other players. This article focuses on the design phase of the game development process and highlights the role of some techniques that can be used to design a successful educational video game (guidelines and design patterns). These techniques provide information on good practice and form a basis for evaluating the educational video game quality, acting as useful tools for developers to enhance video game playability. To this end, we have presented a set of guidelines and design patterns in order to provide an acceptable level of playability and, in this way, a better player experiences and learning achievement."

Abstract :"Petri nets are graphical and mathematical tool for modeling, analyzing, and designing discrete event applicable to many systems. They can be applied to game design too, especially to design serous game. This paper describes an alternative approach to the modeling of serious game systems and classification of motivation behavior with Petri nets. To assess the motivation level of player ability, this research aims at Motivation Behavior Game (MBG). MBG improves this motivation concept to monitor how players interact with the game. This modeling employs Learning Vector Quantization (LVQ) for optimizing the motivation behavior input classification of the player. MBG may provide information when a player needs help or when he wants a formidable challenge. The game will provide the appropriate tasks according to players' ability. MBG will help balance the emotions of players, so players do not get bored and frustrated. Players have a high interest to finish the game if the players are emotionally stable. Interest of the players strongly supports the procedural learning in a serious game."

"The high cost of launching resources from the Earth's surface is a significant barrier to future long- duration human space exploration. A future resource economy in space may allow resource production, processing, storage, and transportation at distributed locations, but will have many stakeholders with var- ied and potentially competing objectives. Simulation games provide a medium for communication and learning richer than papers or linear presentations by combining the technical capabilities of simulation models with human interaction. Building on technology powering military wargames, federated simulation architectures such as HLA-Evolved use independently-developed simulation models connected over a dis- tributed network of computers. This paper presents an approach for developing a multi-player simulation gaming environment where human players take on roles of organizations or government agencies within scenarios designed to address the design and operation of a resource economy in space. The game design addresses the number of players, time advancement, level of abstraction, scenario selection, and other de- cisions based on past simulation games in the domains of military-political, educational, disaster response, and business-management games. Future research will focus on evaluating game executions to analyze human decision-making under various scenarios. Quantitative analysis of decisions using game logs com- bined with qualitative analysis of interviews and surveys will contribute to strategies for a future resource economy in space."
