My single favorite non-fiction work. (Probably better than any fiction I've read, too) Even if you're not a gamer, this book has such a great story and has so much to offer when it comes to software development in general.
Same here. I read this every year -- it motivates me like no other work or fiction or reality. I bought a few copies for friends, and it seems to have similar effects on them. I can't recommend it enough.
You may also like "Racing the beam", which is not so long on human interest but has a lot of great technical, social and business perspective on the Atari era.
