Guitar Hero is the best game ever created.  I've played it, and mega man is roadkill on the street compared to it.  OMG it is amazing!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

My answer is, just buy Guitar Hero for the console.... because it is a better experience and I would not be used to it anyways, so take this advice into consideration, because I have GH on the DS, and it isn't that good of a game, it lags ALOT.

What a coincidence, I have GH for the DS, it really does blow.
