I know 360 ownership here isn't exactly booming, but if any of you got 360s for Sonic I strongly suggest you get this game, it really proves that there is actually a point to the next generation. The amount of times I've looked at the graphics and gone "holy ____", and the gameplay is very fun. Plus it has two of the best weapons ever placed in a game; the chainsaw gun which is just hilarious, and the explosive bow which has the most awesome aiming crosshair ever.
If anyone does get it, or has it, add me to your friends list, because the multiplayer is almost better than Halo 2, and can be incredibly funny when you sneak up on someone with a grenade and stick it to their face.
