No, I didn't buy GHWT, GHM or GHSH. I played the GHM demo, though. Stone Cold Crazy on Expert.
1: The GHWT guitar is shit. The bridge is where my hand rests, the buttons are too recessed, it doesn't have a d-pad, the start buttons are fucking tiny.
2: The note timing sucks. I was hitting nots EXACTLY on time, and it didn't register as being hit. Gay.
3: The interface looks like shit. The gay "slider ropes" look fucked up, and the circluar notes are so 2006.
4: The chart was horrid.
All in all, GHWT, GHM and GHSH are shit. Complete and total shit.
