...I unlocked all songs on Rock Band, does that count?
Oh, just kidding. I'm not planning to write a review before I at least get five stars in all songs. I'm also dying to play on the Hard level, but I'm still too slow for this. Finishing all songs with five stars is just a warm up. And I only finished the game using the guitar anyway. I'll NOT finish it using the microphone since I hate singing and my singing skills are lame, but I'll DEFINITELY have to finish the game using the drums.
Until now, I can say the game play has a good timeof response, the songs selection in general is good and the game is fun (even though it is not as fun as playing with your friends).
...yeah, I bought a 360. And a couple of games for it, but I'll play them like crazy only when I finish Rock Band. Well, at least in the guitar. Or as soon as the weekend comes.
