Hi I dont have these games but i have played them.First well starton Roack Band 3 wow this is a really cool game you have the kea board 105 note guitar i think and a big drum.You can also have 3 people sing at one.I played the pro drums on expert when i played it because im really good at the drums and the guitar.I wasn,t very good at the kea board.The guitar was hard. But it was really fun.Now lets talk about the power gig ok a real guitar sencor drums and the microphone. Ok the guitar was a good idea but the drums are sencored and they dont look fun it was funner hitting stuff then fighting the wind. and the microphone they called it the mojo vaux. Thats it you persons tell me witch one you like better kkk se yalll bye.
