Games Radar recently went to the trouble of comparing the guitar track difficulty in both Rock Band and Guitar Hero III. We've mentioned the fear that Rock Band would have simpler guitar than Guitar Hero III, and according to Games Radar, that fear is not unfounded at all. After directly comparing some of the songs available on both titles, Games Radar has come to the conclusion that Guitar Hero III on Hard is equivalent to Guitar Hero II on Expert. Rock Band, on Expert, on the other hand, is equivalent to Guitar Hero II on Hard. But don't take our word for it, check out the video comparisons for yourself. Part one is embedded above, and part two is embedded after the break.
