Hey gamers! Do you know any RPG games similar to Neverwinter Nights?

I just played Neverwinter Nights 1 and 2 and was fascinated by them. Do you people know any similar games (sci-fi, fantasy.... anything). I played Icewind Dale. But it is too archaic. If you recommend RPG-action, like DemonStone, or RPG-strategy, like Warlords Battlecry, that will do too....
