Fallout 3 Interview

The IGN Game Scoop! podcast features an interview with Bethesda's PR head Pete Hines, asking some fresh questions about Fallout 3 and getting a few tidbits of new info. This includes the worldmap featuring Oblivion's type of fast travel, creatures respawning only if it makes sense, and karma only being affected when you're caught.
IGN: one thing we didn't see [in the demo] was the overworld map, how you actually get around in the world. In Fallout people told you about a city and you could travel there in an overworld map, but then you could encounter random enemies on the way. Whereas in Oblivion you would just fasttravel there.

Pete Hines:
In Fallout they used this method of traveling across the world that was dissociated with actually having to walk across it. You were a little x moving across the map and you could actually explore unexplored parts of the world. In Oblivion, the difference was that you could never fasttravel until you have been there, so even when you know where a place is you can't actually fasttravel to it or back from it until you've discovered it. I imagine that whatever we end up doing in Fallout 3 will be similar to that. We don't want you to skip the step of going out into the world and finding new things to do and to just be able to jump in. We like the fact that you have to get there first and have made your way to it, and then, if you're going back and forth between two places you've already discovered, there's no reason you can't just jump back and forth. But how exactly fasttravel will work in Fallout is still TBD.
