The subtitle is “for game design” and it takes the definition of ‘game’ widely.
The basic idea is that learning is naturally done by games: games to rehearse, games that practice skills, games that visualise abstract concepts, simplify concepts or allow us to try things in a safe arena. The book doesn’t try to provide a cookbook for a fun game (ie: ‘you should have a cute character’) but instead looks at what makes our brains tick when we enjoy and have fun with a game. By taking a wider more generalised view, some very interesting thoughts are triggered: and that shows the skill of the author. He has created a book that listens to its own words - its fun, very readable (half of it is in cartoon form!) yet makes complex points in very simple ways:- definitely an ‘out the box’ type of author! If you’re remotely interested in developing games, this is a great thought provoking book. It would perhaps benefit by some case examples of fun games analysed in the books context, but that’s perhaps deliberately left to the reader.
