GH3 fans will be letdown. Plus Rockband is so much better.
The setlists in this game are pretty much a joke save for a couple near the end. I found virtually no pleasure or challenge beating this game in a few hours unlike the weeks of practice I had to do to just beat TTFAF on expert in GH3. The songs themselves aren't very good or appealing I think to the majority of people that play GH, a lot a bit too old or too slow for many tastes.
Online play has been destroyed thanks to removing the ability to duel people on the same difficulty level. THERE IS NO PRO FACE OFF! Online is filled with kids playing on medium and hard so they can cheat their way into a win. Finding no difficulty in the singleplayer I was hoping the multiplayer would offer some challenge but sadly no.
And Finally, The game just doesn't feel right. For this installment of GH they decided to tighten the notes up, you cant finger flail your way through a lot of tough sections like in GH3 which I don't mind except the feeling of the game is all off. I can't really describe it, even though the tightness is along the lines of rockband's... I just flat out hate the feeling of playing GH4. I loved playing GH1, 2, and 3 plus Rockband 1 and 2, yet GH4 doesn't seem to ring the same bells.
Add to all this the fact that the peripherals are just as shoddy and weak as rockbands, as well as the fact that the new purple bar on the guitars is impossible to use, I say stay far away from this game. I feel many GH fans are going to be let down by this game.
