C'mon guys give Neverwinter Nights a GOOD try!
The power of that game lies in multiplayer, the 3th edition rules AND making mods (the aurora toolset)

Why do you think they'll be releasing a few add-ons? Not for singleplayer... To keep the modders at work! New tilesets, enhanced toolset, great new items and spells, classes, ...

I agree, Baldur's Gate II or <img src="/ubbthreads/images/graemlins/div.gif" alt="" /> "look" very nice and play much better in Single player. But it's fun too with NWN to play together with some friends defeating a dragon or two..
