Though They Tried To Be Innovative with the Drum Set, the Band Play Is Bottom Of The Barrel Material (Opposed to RB2)
Pros:
-GH-Mix Music Creator (Which Does Get Boring After About 20 Mins)
-Cymbals on The Drums Work Perfectly
-Guitar Works Fine
Cons:
-Band Play Is Total Garbage (Just Like GH3 Co-Op, but With Drums and Vocals Included) Compared To Rock Band 2
-Drum Pads (Not Cymbals) Are Not very sensitive and require a hard hit to get them to register notes (Or They Sometimes Don't Register Notes at All)
-And Overall, Mostly Everything Was Cheaply Made
So In My Opinion, Stick With Rock Band 2 If You Like Playing With Your Buddies. As well, If Your Still REALLY want this game, Make Sure You Buy It From a Store that has some sort of return policy if you're not satisfied. (I Don't Think Anyone wants to be Out $200 for Something They Won't Use)
