Hi there,
I'm new to the site, and have been working in the game industry for 2 years now. In an effort to improve my work and knowledge about games, I want to read some books on Game Design. I read The Art of Game Design by Jesse Schell when I first started working. Other than that, I haven't read much else, so I'm looking to get some help. If you had to recommend say 3 game design books, what would they be?
