is there any reason not to buy rock band?

i loved guitar hero 3 so much and now i realy want rock band. apart from the price is there any bad reason not to buy it?

i had no lag issues with guitar hero 3 it worked perfect. is there any problems with any of the hardware with it? does the game play well and are the songs in it as good as guitar hero 3?

Well, if you don't have any arms or feet, you shouldn't buy this game

Edit: Or if you are a dog

The only reason not to buy it is if you are a deff blind mute with no appendages. If you love rhythm games, this is the one to get. And the so called "high price" is worth is for what you get.W3dotCOM
