Personally, I think that Rock Band beats Guitar Hero 3 in music choice as well as graphics and overall feel. That said, Guitar Hero 3 is the WORST edition of Guitar Hero to come out. But I still think that Rock Band is better overall. Sure, there are areas where it can improve. But Rock Band beats Guitar Hero 3 by far. The only downside of it to me was the cost.
rockband is so much better, in GH ther's only guitar..on rockband u can do everything on GH plus use additional 2 instruments....u ot the guitar drums and u can sing, rockband panz gh
for guitar, obviously GH3, but Rock band for being able to play drums and sing. I think GH3, because I love playing real guitar and that makes me good at it, and Rockband's guitar sucks
GH3 is game that you could play by yourself and rockband is like a multiply person game so i would take GH3 because i would only play it myself so it would be easier
