Quick question - can you use the Rock Band guitar, microphone, and drums when playing the new Guitar Hero World Tour game (on the Wii)?
You can use the microphone, but not the others.
I read that the Rock Band 2 and GH World Tour instruments could be used with each other, but not the original Rock Band instruments.
I don’t own either, so I can’t verify either way. But want both, and have been doing some research into it. Hopefully this is accurate because at some point I want to buy a full version of one and just the game of the other.
Joystiq has a hand compatibility Matrix that shows what instruments work with which games (Wii’s near the bottom):
