As others have pointed out, though, this is Bethesda's official forum, and Bethesda hasn't made a turn-based game... well, ever, as far as I know. So it's safe to assume that, on other forums not so strongly biased against turn-based games, you'd see a 75%-25% split in favor of turn-based gameplay.
Therefore, about half of computer gamers would probably have preferred turn-based gameplay for Fallout 3 (and perhaps other games as well).
Problem is, the turn-based fans don't get any turn-based games these days. 95% of all new releases are real-time (including strategy games), many are first-person view centric, and if a game wasn't real-time before, the developer takes it and makes it real-time.
So perhaps you can understand why turn-based fans get a little pissy and agitated in discussions like this one.
