I'm getting a wii guitar controller with my Christmas money. I would like one that is compatible with as many different games as possible. Will the official Guitar Hero World Tour work with RockBand 2 or RockBand? How about the RockBand/Rockband 2 controller, will it work with any guitar hero games? Is there one controller (not by Activision or Harmonix) that will work with GWHT, GH3, RB, RB2. Also, is there a modified version of RB2/GHWT made to use the others instruments (not talking about GH with a RockBand playlist, though) There seems to be a lot of conflicting information on the subject. Thanks in advance.
