Im gonna be getting an Xbox 360 friday and I need some recommendations for good but cheap games. I'm already thinking Fable 2 since I've always wanted to try it cause I loved Fable TLC, and it's only 8 bucks pre-owned at gamestop.

Anyway recommend some some good yet cheap Xbox 360 games.

Fable III sucks. It's so boring.

I think GTA IV's down to like $17 now.

The Orange Box is good if you don't have all the games on PC, plus you can play vanilla TF2.
Burnout Paradise from the on demand market place is great to.

That game is hacked into oblivion.  Get it for PC.  I'm not saying this to be an elitist, but admins can just ban cheaters off the server.

Get Halo! (Not sure if regular Halo is cheap.)

[Squideey]

Two arcade titles.

Shadow Complex and Bastion.

I heard Limbo was good.
