TES IV Oblivion

No questions asked . Played it for two years. And you could still be if you want to continue, if all the monsters with me already greet started :)) also fall into this category and Sims

I understand there is meant the longest storyline . Then none of Simonov not suitable . The Sims is a simulator and plot there . In Obvilion not played , but apparently worth it .)) If it people years play , and yet the longest I think GTA4 , I suppose it was very long .

Sims 2,3
Gta SA,IV.

World of Warcraft, every single long, simply can not be, the same Oblivion you can if you want to go for a week and forget all
