Testing the PC gaming waters. What games can/should I try out with my PC?

[ishiki]

Neverwinter Nights, Neverwinter Nights 2 (Especially Mask of the Betrayer if Story is what you want), Starcraft 2 if you like strategy games.

They're like KoToR only a lot deeper (and use same engine :P), Dragon Age (except if I remember the dragon age controls are aweful on console).
