Yes, it should.
Yes the guitar hero world tour (4) controller will work with guitar hero 3 on any system
Yes, it works for all the Guitar heroes that came after Guitar Hero 3
No, you can use the guitar hero 3 controller, which is wireless, for guitar hero two
IT does for Guitar Hero 3, World Tour and Metallica. Not for Guitar Hero 2
u cannot use the gh3 guitar for ps2 for the PC
That completely depends. Is the guitar hero 3 controller for the same platform as the guitar hero 2 controller ? (I.e. xbox 360 or ps2)
yes
Yes.
probably, because the guitar is meant to be used on other games on the same console that is.
