For the guitar alone, Guitar Hero is much more difficult and much more exciting. I my opinion, it has better songs and there's a "story". Rock band is AWESOME if you actually have a group of friends to start a band. By far one of the most bonding experiences I've had.
I have many problems with Rock Band 2.Such as.....
-The songs are not that great. -The drum design is pwned by the one for GH World tour. -The hammer ons for the guitar totally suck!(Biggest Reason) -HAS NO SONG CREATOR.(as apposed to World tour) -The guitar has no figer sliding motion sensor thing.(GH does)
Do I have to keep going!?!? World tour is so much better!!!!
