I read the exclusive preview of it and check out a film about how the game's like. It really looks neat. NWN will still be better, but I think I'll buy Dungeon Siege as well. For anyone that doesn't know about this game, it's a Diablo+BG kinda game, though way better then Diablo.
For anyone that's from Europe and interested in the preview, it's in the game magazine, PC Games, it's German though :S
