I wish it were just about the cave - that'd be fun! I'm afraid my book is about all kinds of "Counterplay" - the use of glitches and exploitable spots are just one example.

I see, interesting. *no sarcasm* So it's topics about finding loopholes in games, or in anything?

Exactly. Its about the different ways that people play on videogames beyond the convential, beyond the rules and even against the law: boosting, grief play, glitching, incendiary ugc, hardware hacking and modding. - its overtly a non-judgmental study though. Trying to understand what is done and why, as opposed to suggesting that if you do X you are a certain kind of player. Its my PhD thesis, but expanded and for a more general audience.
