Hmmm… great post. I’ve read a few of these, and agree with your recommendation. I’ll definitely be checking out some of your other suggestions. I’ve been trying to get my hands on Csikszentmihalyi for a while now, but it’s been hard to find around town.
Two other not explicitly game related, but important books with great insight:
Dietrich Dorner; The Logic of Failure
Alan Cooper; The Imates are Running the Asylum
