Things We Think About Games is an exceptionally quick read, fun and thought provoking. Much of the book is a collection of short, sharp sayings. Much of the work is in the interpretation-- sometimes that author takes up the challenge, writing up to a page of discussion-- and sometimes the analysis is up to you, only a quickly sentence is provided.
It's a fast read that might shake loose some dangling thoughts. It's probably more useful to designers, to make sure they're not falling into traps, but there's a little something here for everyone. I'll happily lend it to locals if they want to look it over.
