I have the wii GH:WT, though i only bought the game itself as i didnt have enough monies to get the full kit or game + guitar as i wanted to play it this weeekend and not wait till i did but i'm liking it so far.
Need to get drum and guitar for it though, as in proper GH:WT guitar.
I have no issues with the Wii version, granted its the same as the rest but probably not as "shiney" but meh.
Also, i found a store that's been selling anime for the past few months so woot to me, as i havent been able to buy at a physical store for a couple years now, all online for me otherwise.
