I'm not a developer of course but I've always enjoyed reading about how games are designed and built. I read through the article on System Shock II. Playing through the game you would never guess the development woes because it is such an intense game. You don't care what the AI is capable of as long as it doesn't kill you on the spot. I'll be reading all of these then hitting the older archives.
Presented by Alex Waro from Gamasutra's "postmortem archives" developers talk about what went right and what went wrong as they worked on classic games.
