This might sound stupid, but I'm wondering if I bought LEGO Rock Band for the Wii for my brother, will Guitar Hero work with the Rock Band guitar/drum/mic?
Sometimes they're compatible, sometimes not. According to this chart -- http://www.rockband.com/compatibility …the answer is a no. If it was on the PS3 or 360 the answer would be yes, but not on the Wii unfortunately. On the Wii: - Lego Rock Band (game) will work on Guitar Hero equipment, but… - Guitar Hero (game) won't work on Rock Band equipment. So what I would do, is buy Guitar Hero World tour with the drum kit and guitar etc. and buy Lego Rock Band separately to play on it.
Well I play my guitar from GH in RockBand and use the drums from RB on GH so I guess yes. This is for the 360 BTW
The GH and RB devs made a deal that in future all their instruments would be cross compatible across each others games (although there may be missing features), however there are some cases (like the Wii versions) where it doesn't work... possibly because Wii games are near impossible to update.
