A theory of fun is written by Raph Koster. Mixing cartoons and text to get the message across is interesting. He basically says games are entertainment and puzzles but still teach humans many skills. Skills that can be used in the real world. In a sense, Koster breaks down society and how they interpret art and craft, as well as games in general. He points out that games have evolved from rudimentary games such as tic-tac-toe into something much more. Players want more from games, and the game developers try their best to do so. Games with more than one answer should be focused upon. With the improvement of technology games are beginning to take on a new role in society. One in which certain circumstances yield far different results.
