Im a big fan of Shooters but the problem is they get boring an repetative. Im thinkin an RPG like Oblivion or something. Does any1 have any suggestions

Forza 2 will last you forever with a beefy single player, great multiplayer, and deep customization.

Two Worlds comes out in July, and that should last you quite a while since it's like Oblivion.
