7 - Guitar Hero 3 (Xbox 360)
Rhythm games are a fad. They're not real games. And yes, my opinion probably has everything to do with the fact that I suck at them. And look, just because I had a moment of weakness and let myself enjoy GH3, does not mean that I'm interested in hearing you talk about how awesome Rock Band is going to be. I don't care. Hitting dodgy plastic buttons on fake plastic instruments is never going to be as fun as the real thing, and I should know.
But yes, I'll admit it: I can now at least see why people enjoy this series so much. It is fun. It's amazing how hitting buttons in response to little coloured circles on-screen can actually make you feel like you're a rock star. Oh, and it helps that the tracklist in GH3 is pretty damn superb as well.
So there. A rhythm game in my top ten of 2007. Something you won't see in my 2008 top ten. Nosir.
