Abstract: "Immanuel Kant's categorical imperative, stating (in one for- mulation) that one ought to always act according to a maxim that can be made universal law, is tempting to procedural- ize, in the form of a game that literally turns actions into universal laws. This paper explores diculties that initially arise in translating that idea to a game design: some of which been covered in the philosophy literature, and others of which relate to the diculties in dening what constitutes a proper rule induction. Then, it discusses several much less lofty, but ppractical, prototypes that explore what I take to be the formal game mechanics underpinning the idea: re ex- ive game mechanics where breaking a rule implies the free breaking of that rule for the rest of the game. By analyzing these prototypes, I attempt to determine if these prototypes result in either an interesting game mechanics (taken on its own) on the one hand, or a compelling representation of Kantian morality on the other hand, reaching mixed con- clusions."

"In this paper we present an ap- proach for serious game development, based on the model-driven game development techniques. Our approach aims at reducing the complexity of game design and implementation by separating the conceptual envi- ronment of the game and its concrete implementation.We rst dene the abstract models that characterize the structure and behavior of the game. Then, with the software architecture model and the platform-specic model, we transform the abstract models into concrete implementations. The resulting prototypes are generated completely (100%)."

"Strokes are a leading cause of death and disability and have been described as a "worldwide epidemic" [5]. Strokes cause disability, partial paralysis and leave up to 85% of their victims with some form of motor impairment. Stroke rehabilitation starts as soon as possible and involves repetitive movement which people find repetitive and boring. A study [1] has found that as few as 31% of people complete their exercises as recommended. Adding to this the high cost of one on one therapy and transport to see specialists, stroke rehabilitation is a major problem. Games have been trialed for stroke rehabilitation to increase patient motivation and reduce costs. This literature review aims to find out to what extent games have therapeutic value and further, what characteristics make a good game for stroke rehabilitation. We find that in order for a game to be successful it must be based on solid therapeutic principles as well as game design principles including "challenge" and "meaningful feedback". Different hardware and software can be used as long as it follows game design principles to encourage patients to perform therapeutic exercises. Games must also take into account the low morale of recent stroke victims and avoid discouraging beginners."
