Rock band is definatly worth your 170$. This game is the best party game ever made. You can play the drums, mic., and gutitar. You can even make your own character . I recommend getting this game at your local gamestop. The guitar is basically the same as guitar hero except you have 5 buttons at the lower part of guitar for solos. The drums are my favoite insturment. But you need to be careful with the pedal it can break. Rock bands songs are awesome to. They are realsing new songs for download via Xbox live. This game has a lot more value than the guitar hero games but i still love gutar hero to death. If you like this game you should also get guitar hero 3.
