Baldur's Gate or NWN?

Baldur's Gate 1, BG2, Neverwinter Nights? Or perhaps Fallout 1/2?
Or another game (guess you get the picture what kind of game I want)?

Yes.

BG is just a slightly more interesting Diablo2. But if you've played D2, BG won't have enough new stuff to warrant getting it.

NWN has good campaigns. Lots of quality usermade content, including the PRC pack (nwnprc.netgamers.co.uk). The official campaign does start you out with retardedly simple battles, yes. It is designed to be accesible to people who have never even heard of D&D before, and get them used to turn based RPG combat, so it is more of a tutorial for the rest of the game.
