I have found after playing practically all of the guitar hero games, this one is slightly easier than the rest of the titles; most noteably guitar hero 3 which is by far the hardest.
But this is by far the best game to play in a large group! Everybody knows the songs and everybody wants to play so it really adds to the fun.
Pretty much the same though if you are on your own but for any guitar hero fan it really is a must!

I must admit I was very skeptical when this title was announced but as a dedicated fan of the Guitar Hero games I decided to risk the purchase and I'm glad I did.

Yes, the track list is very pop, but there are some classic songs in there and quite a few rock tunes and the variety is as good as any previous in the Hero series. But by far the best thing about the track list is that we finally have a music based game that my 7 year old daughter and I can play together. Beginner mode is a revelation and makes the game easy enough for her to play without over-simplifying the game.

The actual gameplay doesn't differ much from Guitar Hero 5, same graphical polish, same menu system, same drop in drop out mechanic etc

I think Neversoft have achieved what they set out to do, create a rhythm based game that literally everyone can enjoy!
