I don't know - they don't take much time if no one releases any, which for PCs has pretty much been the case since KOTOR 2 came out last year unless you count weird European/Russian stuff or Jeff Vogel's budget games.

Believe me, an MMO will suck the living out of you. I have several friends who think that 8-12 hour session of WoW/day is avarage.
And since there are no newer games to play, i've gone retro and i'm currently fighting guards in Curst underground prison in Planescape: Torment
