It's funny because on the same day I exchanged my GHWT Guitar Kit at Target I went next door to Gamestop and I saw a copy of Rock Revolution for $20. I decided to buy it out of curiosity. Some covers fail in the vocals (e.g. Cum on Feel The Noize, Were Not Gonna Take It, All the Small Things, My Dirty Little Secret, Highway Star, Run To The Hills ) but for some their just okay. Was it worth the $20 I spent IMHO? Yeah I think so. I play through short bursts through Quickplay plus all the tracks are all there for your shredding needs (no need for career mode to open them up). So far Lita Ford's Kiss Me Deadly is my favorite song.
