"As research for a Ph.D. thesis, we propose to show that a layered Statechart-based AI is a suitable formalism for Game AI, enabling the use of model-driven development techniques such as reuse and high-level analysis including model-checking. The fundamentally modular nature of this approach leads naturally to reuse as a fundamental component of the design process. Supported by a clearly defined formalism, useful behavioural analyses become possible, such as testing reactions to various inputs at design time. We also explore transformations at the modelling level to enable procedural generation, allowing rapid deployment of varying AIs. Additionally, such a model allows for the generation of efficient code that can be directly inserted into games. Tool support for reuse, generation, and analysis will be developed, then employed in creating an industrial scale AI, proving that this formalism is appropriate for industrial use."

A discussion of frustrations with not being able to make the next level and see other parts of the game, with examples

Abstract: "With the growing availability of personal communication devices we are witnessing a tremendous increase in the demand for mobile services based on location and context. Mobile gaming is, of course, following this same trend. Unfortunately, differently from other services, location- and context-based gaming strictly requires near-field communication to interact with nearby players in order to create teams and arenas. Since currently adopted technologies suffer from scalability (Bluetooth) or energy (WiFi) constraints, Opportunistic Networks (ONs) have already been addressed as a viable solution to involve a considerable number of players on a wider area. While massive multiplayer games are commonplace on wired networks, it is not yet clear how player experience is affected by the increased delay and probabilistic message forwarding introduced by a huge population over an ON. In this paper we address this problem by proposing an opportunistic collaborative game, which is meaningful for the category of collaborative puzzle games, and evaluating its playability and scalability by means of simulations on a real city topology."

Abstract: "We propose a powerful new tool for conducting research on computational intelligence and games. 'PyVGDL' is a simple, high-level description language for 2D video games, and the accompanying software library permits parsing and instantly playing those games. The streamlined design of the language is based on defining locations and dynamics for simple building blocks, and the interaction effects when such objects collide, all of which are provided in a rich ontology. It can be used to quickly design games, without needing to deal with control structures, and the concise language is also accessible to generative approaches. We show how the dynamics of many classical games can be generated from a few lines of PyVGDL."

Abstract: "Game design and development still needs complex technical skills that only some people master. This can be a huge barrier to game creation by end-users limiting the emergence of a participatory culture around games - similar to the one we have seen with Web 2.0. While there have been approaches to lessen that problem, such as level editors and content creation tools, we think we could go further. We propose that considering and developing design interfaces that make use of common natural skills such as drawing could be a key step to achieve that phenomenon. Therefore we describe and present the Playsketch concept, and it's current implementation, a game creation approach based on the Paper Prototyping concept which invites the users to create simple personalized games."

Conducted and written by Dr. John Richards, Leslie Stebbins and Dr. Kurt Moellering, the report synthesizes findings from extensive market research and a series of fifty interviews with leaders in the developer and publishing industries, and from the government, foundation and research sectors."

Abstract: "In on-line role-playing games (RPG), each race holds some attributes and skills. Each skill contains several abilities such as physical damage, hit rate, etc. Parts of the attributes and all the abilities are a function of the character's level, which are called Ability-Increasing Functions (AIFs). A well-balanced on-line RPG is characterized by having a set of well-balanced AIFs. In this paper, we propose an evolutionary design method, including integration with an improved Probabilistic Incremental Program Evolution (PIPE) and a Cooperative Coevolutionary Algorithm (CCEA), for on-line RPGs to maintain the game balance. Moreover, we construct a simplest turn-based game model and perform a series of experiments based on it. The results indicate that the proposed method is able to obtain a set of well-balanced AIFs effi-ciently. They also show that in this case the CCEA outperforms the simple genetic algorithm, and that the capability of PIPE has been significantly improved through the improvement work."

"effect of game reviews on player experience and perceptions of quality. We show that negative reviews cause a significant effect on how players perceive their in-game experience, and that this effect is a post-play cognitive rationalization of the play experience with the previously-read review text. To address this effect we designed and deployed a new heuristic evaluation technique that specifically uses game reviews to create a fine-grained prioritized list of usability problems based on the frequency, impact, and persistence of each problem. By using our technique we are able to address the most common usability problems identified by game reviews, thus reducing the overall level of negativity found within the review text. Our approach helps to control and eliminate the snowballing effect that can be produced by players reading reviews and subsequently posting their own reviews, and thus improve the commercial success of a game."

A blog by a recent game design graduate features posts about "presence in games," creating levels and other ideas and commentary, also potentially serving as the author's portfolio.

"This article is about the learning that occurs from making games, rather than from playing games. In this paper, we describe the use of Rapid Digital Game Creation (RDGC) for learning and teaching Object-Oriented (O-O) concepts. RDGC involves the rapid building of digital games with high-level software that requires little or no programming knowledge. We examine how RDGC supports the understanding of various O-O concepts. Using a theoretical framework of constructionism, we discuss pedagogical guidelines for RDGC-based learning. We suggest that RDGC is a useful pedagogic tool that complements formal programming languages and can help flatten the steep learning curve needed to learn O-O computer programming (or OOP)."

"This paper presents the theoretical foundations of and the research methodologies for designing, developing, and evaluating stealth assessments in digital games. ... There are four main sections in this paper. First, we discuss problems with existing traditional assessments. Second, we review evidence relating to digital games and learning. Third, we define and then illustrate our stealth assessment approach with a set of assessments we are currently developing and embedding in a digital game (Newton's Playground). The stealth assessments are intended to measure levels of creativity, persistence, and conceptual understanding of Newtonian physics during game play. Finally, we discuss future research and issues related to stealth assessment in education."

Abstract:"A one-semester introductory undergraduate course in computer game development is described. The freshman-level course has been taught for four years. The course was designed and implemented in the context of a new curriculum in computer game development. Goals of the course were to retain undergraduate computer science (CS) majors, attract new students to CS, and expose students to the content creation pipeline used in more advanced courses. A significant aspect of the course is the end-of-semester project to create a machinima - a video created using computer game technology. Besides the initial goals for the course, other benefits were discovered including fostering a sense of community by helping students get to know their peers early in the program. Results, both quantitative and anecdotal, show the course has exceeded expectations in meeting the goals originally established. In addition, the course content has been adapted to the format of a three-day summer workshop to recruit high school students to the university. The course has been integral to the growth of the CS program, enabling the program to nearly triple in size over four years and achieve both statewide prominence and national recognition."

Abstract: "Collision avoidance and multi-agent navigation is an important component of modern video games. Recent developments in commodity hardware, in particular the utilization of multi-core and many-core architectures in personal computers and consoles are allowing large numbers of virtual agents to be incorporated into game levels in increasing numbers. We present the hybrid reciprocal velocity obstacle and optimal reciprocal collision avoidance methods for reciprocal collision avoidance and navigation in video games and described their implementations in C++ as HRVO Library and RVO2 Library. The libraries can efficiently simulate groups of twenty-five to one thousand virtual agents in dense conditions and around moving and static obstacles."

"Abstract-While component reuse is a common concept in software engineering, it does not yet have a strong foothold in Computer Game development, in particular the development of computer-controlled game characters. In this work, we take a modular Statechart-based game AI modelling approach and develop a reuse strategy to enable fast development of new AIs. This is aided through the creation of a standardized interface for Statechart modules in a layered architecture. Reuse is enabled at a high-level through functional groups that encapsulate behaviour. These concepts are solidified with the development of the SkyAI tool. SkyAI enables a developer to build and work with a library of modular components to develop new AIs by composing modules, and then output the resulting product to an existing game. Efficacy is demonstrated by reusing AI components from a tank to quickly make a much different AI for a simple animal."

"The Kamloops-Thompson school district is taking its video-game design curriculum to the next level. What started as a summer-camp program in 2007 and grew into a limited course offering last year is set to assume full-course status - meaning area high school students will have the opportunity to spend an entire semester studying nothing but video-game design."

"browser game using CSS3 metaqueries ...After starting the game it will show you 2 pixel values, the first represents the width, the second one the height. Your task, if you choose to accept, is to resize your browser window as fast as possible to the presented width and height. The background color of the webpage indicates whether you're far off the pixel values or not. Blue means "far off", red means "almost there" and green "you've done it." The countdown in the middle shows how much time is left to resize your window. Depending on what game level you choose you have to be more or less precise and faster with the resizing. "

Abstract: "This paper introduces Rank-based Interactive Evo- lution (RIE) which is an alternative to interactive evolution driven by computational models of user preferences to generate personalized content. In RIE, the computational models are adapted to the preferences of users which, in turn, are used as fitness functions for the optimization of the generated content. The preference models are built via ranking-based preference learning, while the content is generated via evolutionary search. The proposed method is evaluated on the creation of strategy game maps, and its performance is tested using artificial agents. Results suggest that RIE is both faster and more robust than standard interactive evolution and outperforms other state-of- the-art interactive evolution approaches"

Abstract: "Teaching computer programming to novices has always posed a major challenge to educators, most novices acquire basic programming skills but they are unable to utilize them in a meaningful way to solve many of the non-routine problems which are presented to them. As a result, they do not achieve any level of programming fluency. Collaboration has been identified as a useful tool to help overcome this problem if utilized at the right times during the programming/problem solving process. This paper presents a review of computer supported collaborative learning (CSCL) concepts, collaboration in programming and the problem solving domain. Finally, a design for a gaming application of CSCL (COPS) to help improve the problem solving ability of novice programmers is presented."
