New interview, Mike Lipari answering this time. Still no question about playing Fallout:
What other games have you worked on?
Morrowind, Oblivion, and their never-ending expansions, translations, and ports. (...)
What would you say is your personal greatest game of all time?
Oblivion. I still find myself hooked on occasion. I start it up to look at a bug in GOTY and find myself sneak shotting bandits just to see their corpses tumble over ledges. If we let nostalgia factor in though, then its probably Contra 3 on the SNES. Back in the day I’d beat it in one man, starting on easy and working up through hard while using only the basic gun, just to kill time.
