Good single player games?

Looking for a new game to play. Has to have good replay value as I don't have online. Considering Dragon Age II or Mass Effect 2. Currently playing Sacred 2 and already played both Fallouts, AC2, Oblivion, GTA IV, Arkham Asylum and the first Dragon Age.

Anybody got any good suggestions?Good single player games?
honestly go with dragon age 2, mass effect is about 10 to 15 hours long depending on weither or not you take time to look through everything and dragon age is 60 hours now they are made by the same company and have similar features as far as customization goes but the main thing you want since you dont have online is replay value and longevityGood single player games?
