Having never been really involved with the Dwarf Fortress community/cult, but having played the game quite a bit, this exposé on the creator is extremely interesting. I always thought it must have taken a certain level of cleverness to build such an impressive simulation, but I honestly didn't think he'd be a Stanford Ph.D. Also, I'm honestly surprised they get that much in donations. It's very well deserved indeed and I'm happy to hear that they do.
