This kind of makes me happy. I really liked a lot of the songs from the first two games. However, they better do it up right:
1) No more covers. Get the master recordings for ALL the new-fangled songs. Otherwise, don't include them.
2) Why not make these downloadable track packs? Cuts costs, shortens turnaround time, consumers can pick which songs they want. For example, I sure as hell don't want "Girlfriend" (GH2), but please give me "Bark at the Moon" (GH1). But if you fail to include "Bones" or "Freebird," I will be very pissed.
So here's what Activision needs to do. Figure out which songs they can get master tracks for. Put those on a disk OR DLC.
