Xbox 360 'must plays'

[Jason]

So, as some of you may know, I'm now in possession of a functioning Xbox 360, and as such will be needing a few games to play on it.

What I'd like is a definitive list of games on the Xbox 360 (bearing in mind I do own a PS3 and am therefore likely to have played many of the major cross-platform games) that I absolutely have to play.

I have played and cleared Halo 3. I might get ODST if I can find it cheap, but I'm undecided on that, as I'd mainly be getting it to see what the Reach beta is like.

I really think ODST is kind of a waste. It's nice to have all the Halo 3 multiplayer maps on one convenient disk to save hard drive space, but the ODST campaign BLOWS. It's so ridiculously easy. The Halo Reach beta is just ok, I can wait until the fall. Unless you get it for a really low price i wouldn't bother.

Other than the Gears games, I don't think there's too much exclusive stuff anymore. Is L4D2 on Ps3?

I know fallout was on Ps3 but at some point the bonus content wasn't available... I'm a bit out of the loop.

Yeah, the Gears games are in the post after a couple of late swoops on ebay.

L4D2 I already have on PC, so I'm not too worried about. I may get it somewhere down the line if it's cheap, but I haven't even finished the PC version, so... :-/

The Fable games, Gears and Halo are about the best 360 exclusive titles around, I believe.

The Assassins Creeds, whilst not bound strictly to console, play much nicer on 360 than PC, too. Other than them, I prefer PC variants than console, but that might just be me. PC fanboy til the bitter end.
