Guitar Hero, in my opinion, is really fun.
But you should never play it for 5 hours straight, the next morning, when I woke up, my hand was so sore, I couldn't move it for like 2 hours.
My favorite songs are, Impulse, TTFAF, Operation Ground and Pound, and Don't Hold Back.
I play on XPERT, my GT is - iTz T o X ii C if anyone want to play sometime.
