I love rhythm games, but Rock Band is the better series at this point. I still play GHIII a lot but tired quickly of World Tour...I heard 5 fixed a lot of the things that were wrong with WT, but that it's still got dumb issues. I dunno, get it if you want it. I wouldn't suggest it if it's your first time getting a full-band rhythm game, because Rock Band 2 is infinitely better.
22 medium-jumbo frets, 3 mini humbuckers, 2 single-coil pickups, and 6 steel strings of pure sex.
