i never played NWN besides a demo or something i cant recall but i think out of the other 2 its BG for surenice story, moral options, dragon slaying ecti also like how unforgiving the game is, i always seem to loose a party member in a fight and got to reload :P

and if theres people that play online im sure BG has the bigger community

cant help but notice that someone put age of Conan for there RPG.. whats that about? even if hes playing beta cant say its the best since its not even a finished product. anyways

FPS: half life 2

RTS:........ starcraft

RPG:hard to say since i consider mostMMOs rpgs so ill split that into 2

single player: fallout 1+2

online: my social life was ruined by everquest 1+2:)

social life for sale. hardly used!

since your question is anwered.. once your bored with that game try half life 2 if your pc can run it its a must have for a pc gamer

RTS:supreme commander for great online battles and medieval 2 total war forgreat single playerand online download the demos to see if you like em

FPS:prey is great single player, you got the games i play online. prey also has a demo.
