I believe World is Not Enough was the best. I liked the levels in multiplayer, and the single player was fun. But, GoldenEye and Nightfire still are amazing. Never tried Quautum Of Solace, though.

1. GH1 is not on 360.

2. If you added that, where is Rock The 80s?

3. Aerosmith will be not as good as any of them, but I am a die hard GH fan so I will buy it. I can't wait until Guitar Hero World Tour :D
