If you like racing games, try Rollcage Stage.

Hmmm... the first thing I would mention is the fact that Oblivion isn't that good. You should have said Morrowind... you should look forward to GUild Wars 2! :)

Hmmm... if you are looking for a science fiction kind game, you should try Deus Ex I, or the so-famous Fallout III. I would recommend you to play The Elder Scrolls III and IV, if you like fantasy RPGs, and maybe Vampire the Masquerade Bloodlines, one of my famous games :)

I hope i helped you at all.

The Elder Scrolls II: Daggerfall :P

Well... it worths it truly. I've got the game from a PC magazine... and I've finnished it two times.

One of the best vampire themed games.

BOOOM! Love by Jack :3

The Eldre Scrolls IV: Oblivion (most of the atmosphere musics)

Arcanum of Steamworks and Magick Obscura, Heroes and Might and Magic series, and of course Warcraft I, II and III :)

Vampire Masquerade: Bloodlines

Team Fortress 2 (:

And, of course easter eggs, especially in Arcanum, TES III Morrowind, Fallout 2 and maybe a lot more which i forgot to mention

What about Diablo III?
