i dunno, i thought KOTOR 1/2 and ME 2 had quite a lot of replay value. i think it has something to do with the relative shortness of those games versus JRPG's and some other western RPG's. now oblivion, which ate over 120 hours of my life (i finished EVERYTHING) is one that i most likely won't ever play again... though i obviously enjoyed it. i'm gearing up to finally start Fallout 3 and then Dragon Age...
