I played Oblivion briefly. While it was fun, and the AI interaction interesting, the endless dungeon crawling, from my prespective and the limited amount of time I played the game, got boring after awhile. It deed seem somewhat Deus Exy, but didn't hold my interest like that one. I should play Oblivion some more and more deeply to see if I can get into it anymore an form a more valid opinion. 10+ hours probably isn't enough to really get a feel for the game.
