i am planning to get a music game for my wii. my choices are, obviously, guitar hero world tour or rock band 2. ive heard amazing things, and although i believe rock band 2 is a more polished game, GHWT has some features you just cant miss. another option, and i kinda like this one, is buying the Rock Band game only and getting guitar, drums, and mic from guitar hero…is this possible?

please answer, and have a reason to support it

 Wii problem which game should i choose!?
