Depends on what you like

Depends on what you like. If you like shooters (and since Halo 3 is a definate buy I'm guessing you do like shooters) I'd suggest Gears of War and Lost Planet. Both are excellent and actually have some semblence of story. If you're into RPGs, I'd suggest Oblivion, and the upcoming Mass Effect and Assassin's Creed. Oblivion, by the way, is the hands down best RPG on any console, or the PC, period. I dare anyone to argue otherwise. (And don't hand me that garbage of "Oh Halo would kick Oblivion's butt". Halo is a shooter, Oblivion is an RPG. You're comparing apples with oranges.)

What kind of games are you looking for?

Shooters:

Gears(It was pretty fun)

BioShock(My Brothers Choice:Extreme Gamer)I havn't played it

Rainbow Six Vegas(I didn't like it nor did my brother, but it's some peoples favorite)

Call of Duty 4(My Choice:Some what casual)

Turn-Base RPG:

Blue Dragon(heard some bad rumors)

Eternal Sonata(GT trailer made it seem like a must have)

Mass Effect(Looks almost as good as Halo 3 without the hype)

Free Roam:

Saints Row(Fun game that does some things even better then GTA: Aiming, pipe bombs and amusing quotes)

Dead Rising(Demo seemed fun)

Assassins Creed

Oblivion(single character RPG) I played for 130 hours

Puzzle games:
