Neverwinter Nights (NWN) is a computer game set in a huge medieval fantasy world of Dungeons and Dragons. This role-playing game (RPG) puts you at the center of an epic tale of faith, war, and betrayal.
Now if I were to rate only the main singleplayer campaign, I'd go with 7 or maybe even 6/10. It's pretty standard for an RPG and doesn't allow much freedom for player. Expansions are fairly better.
But it's the Aurora editor and a **** tone of mods that make this game awesome. I've spent countless hours on making various worlds with it throughout last 6 years, using the tilesets made by developers and by community. It's an awesome feeling to build whole living cities by your own. And you can play with other people.
Other than that, I can say that I like the graphics, I think it's the first fully 3D game made by BioWare. Music is also good (Jeremy Soule!), but I'm fairly sure some of the tracks are variations of the main theme..
