In fact, I would like to see MORE metal appear on Guitar Hero, Rock Star, Sing Star, etc...
Cool.
Consider DragonForce's presence on Guitar Hero to be a gateway, then. Like it or not, they have raised awareness of speedy power metal Out There.
Y'know, the same 'Out There' that doesn't give two shits about the types of bands who play ProgPower, and won't give them a column millimeter of press coverage or two seconds of attention on screen.
--The same 'Out There' that has suddenly sat up and taken note of an incredibly fast, catchy metal band on Guitar Hero.
As the saying goes, "A rising tide lifts all boats."
If metal can be brought back more into the mainstream -- yes, even if it's by DragonForce appearing in Guitar Hero -- then maybe, just maybe, the artists we know and like can actually get some of the credit (and cash) they deserve for their talent.
