10 Grand Theft Auto 4
Like Rock Band, Grand Theft Auto 4's a tossup. If you've got the Xbox 360 build, however, you're a truly lucky gamer. Rockstar Games is still dishing out GTA goodness in the form of episodic content, with great characters and intense new side stories to explore. If you've been itching to get back on Liberty City's streets, try The Lost and Damned or The Ballad of Gay Tony. As if that wasn't enough reason to count this game among the best Xbox 360 games ever, there's always the fact that you can push people in front of trains, saw pedestrians down with helicopter blades, and drive your dinner date off a cliff. Be bad, be wild, and be a menace!
