If you’re the type who loves Psychonauts 2 and physics with equal passion, then Double Fine has just the article for you: “Behind the Code: Designing Raz' Jump.”
What’s it all about? Math and science, basically. But, fun math and science! Math and science that made the game fun! And, in that sense, you probably should read it. If nothing else, I’m fairly sure you can use it for your dissertation.
