I picked up Rock BAnd on it's UK release date and have been surprised how much it has become part of my gaming regime.
I'd previously enjoyed GH, GH2 and GH3 a lot but they never seemed to have as many reasons to keep me coming back. Once the career mode had been exhausted I found myself less interested in returning.
Where Rock Band has really excelled is in keeping the title alive with DLC. Every week I find myself buying some of the new releases and getting back into playing the game all over again. Also, I think the difficulty curve is less demanding than the GH series (excluding the drums which I'm still getting to grips with on Hard) and therefore more enjoyable andfun. GH3 really pushed up the difficulty level and, in my opinion, lost some of the fun along the way.
I though long and hard about buying Rock Band as it was an expensive investment (I could have bought a Wii instead) but I've truly been surprised how much value I've had from it.
Hopefully GH will adopt the Rock Band ethos in World Tour and not make it a hardcore wankfest.
I still have 2 guitar tracks to complete in Expert and I'm making my way through drums on Hard. Time to get back to work.......
.....BTW Harmonix, please let us have a Bass Career mode in RB2.
