GH3 isn't that difficult. I don't own a game in the series, and yet I 5 starred every song in the career mode on Expert. I like how the game progresses in a skill curve; if you can't beat a song, which happens a lot, then obviously you're not ready for the songs after it. With the exception of Lou on Expert, which was a *****. In fact, the only song on it I can't beat is The Devil Went Down to Georgia on Expert, which is sort of like the solo in Through the Fire and the Flames, just twice as difficult and twelve times longer.
