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.

Seconded. There's some technical content in the postmortems, and a lot of practical observations on teams and project management.

Super Meat Boy's postmortem was a great read - the team basically were ten steps away from bankruptcy before the game hit and became massively popular
