Whilst every fan tends to have a different idea of what precisely Fallout 3 should be, there are a few things that most of us are unified on. Are you aware of the strong desires for turn-based combat and the classic 3/4 top-down viewpoint? Do you think pure turn-based combat in an RPG is viable in today's market?
Yes, of course we've heard many of the old-school fans regarding the view and combat resolution. What's viable today? Certainly turn-based combat limits your audience to a small number, but I do find that audiences will come if your game is good enough and the presentation is superb. Ultimately we'll do what we think will be the most fun.
Though I understand a lot of decisions are yet to be made about the game, could you see Bethesda doing an RPG that didn't use first/third person camera angle (like Morrowind) as its default view? Should you decide to explore this direction, is the technology you're developing capable of supporting this viewpoint?
The rendering technology can put cameras anywhere. But don't confuse camera angle with interface and interaction, they're two very different things.
