The official Fallout 3 site is pointing out a GC interview with Eurogamer talking to Pete Hines:
...and MTV's G-Hole has a video featuring Emil, Todd Howard and Istvan Pely (thanks, Briosofreak).Eurogamer: Why exactly did you decide to take up the challenge of a Fallout game in the first place? Was there a really a burning desire to work with the franchise?
Pete Hines: That's honestly how it happened. It was just us sitting around talking about doing something else besides the Elder Scrolls, something RPG-ish, and wondering, what could we do? We had discussions and agreed collectively - seeing as nobody's doing anything with it, if we could get Fallout, we would love to do a Fallout game, because it's both very different from Elder Scrolls and something that a bunch of us really loved as a game and thought we could do well as a franchise. We were sitting there thinking we wanted to play another Fallout game, and if nobody else was going to make one then we might as well do it ourselves. So we did; we went up to our president and our senior management and said, look, can you guys make this happen? And they knew some folks at Interplay and had conversations and worked out how to get it. We're very excited and honoured to be carrying on this franchise.
