A tad different than RB. Looks more "vivid" if that makes any sense? Its really bright and graphics wise I think it looks better. The stages, the little intros, and the crowd.
The characters are nowhere near as good as RB in my opinion though. Sure you can create your own, but they just look a little odd.
I LOVE the gameplay itself though. It beats RB in my opinion with the leveling. In RB there are to many holes when you arent playing on Medium.
On medium on GH, it is almost to a hard type level on RB which I love. I always said medium is to easy and a big jump to hard. Its just me and I can always get better, but medium on GH is fun as hell. I find myself concentrating on to much shit and not failing on hard on RB while on GH its more about playing and really enjoying it. I dont know if that makes any sense.

So far the setlist is pretty SICK.
It has 311..NUFF SAID. I had no idea it did. I go into a venue and BAM...BEAUITIFUL DISASTER!!!!

So far Ive done Freak on a Leash, Hotel California, Space Cowboy or whatever. Really bad ass set list.
Havent played drums or anything as of yet.
I will have to checkout their download content but to be honest, this might be a purchase if their DLC is pretty solid.
It is definitely worth a rental from the RB group.
I give it a very solid 9Cs on the Cnasty scale.
