I've been playing Guitar Hero 2 on Expert...and what they say is true. The game is easy from Easy to Hard...but it gets much harder on Expert. Much harder than Expert in Guitar Hero 1. Why? You have to stretch. The three note chords and the alternating chords really make the game much more difficult, especially for me, a Guitar Hero 1 "veteran" since there wasn't as much finger stretching to do in the first game, if there was any to do at all...

Plus, the songs in Guitar Hero 2 really ARE inferior to the songs in Guitar Hero 1, so it's not really as fun to play...to me at least. It's just the gameplay features, like the multiplayer options and the training mode that makes the game "superior" to Guitar Hero 1. That's messed up and stupid.
