New Xbox 60gb owner. Recommendations?

Helo Xbox owners.

Just stopping by that I finally got an Xbox 60gb. I'd never thought that I'd have both the Ps3 and Xbox360 but I've gorown out that fanboyism.

Anyway, I got LOST ODYSSEY because I'm an RPG nut and I'm getting GOW2 when it comes out. what other games do you recommend that aren''t sports or racing.?

Thanks

have a good one

Oblivion

Halo 3

CoD4

Dead Rising

Mass Effect

Gears Of War

Call of duty 2

Eternal Sonata

Blue dragon

Fable (original xbox)

Bioshock

awesome.

I already have Oblivion on my PS3 and Bioshock and Mass Effect look interesting.

Appreciate the help
