The "Postmortems" book from Game Developer Magazine has a bunch of similar stories about Diablo 2, Thief, Deus Ex, AoE, and more.

Quite a few of the late-90s post mortems (post morta?) were collected in a book called Postmortems from Game Developer, which I learned about from Coding Horror.

There's a kindle edition too. Recommended reading IMO.
