It's not that the NWN OC sucked royally, it's also the fact that the control scheme for NWN is very awkward (add the multiplayer lag and it's almost unplayable). I just totally hate the way the character moves when it turns, how the pathfinding works, and all the cameras are stupidly designed. The graphics are horrible (the tiling and map size removes any personality in the game). The character models are extremely ugly too. There's no party option. All this makes the immersion factor at an absolute zero.
All this makes NWN sucks real, real bad in my opinion. This could still have been a winner with a Bioware-quality OC, but instead it's a stinker with a OC that the fan-created campaigns beat easily.
