guitar heroes came from a time when the instrument (electric anyways) was still being explored, many new alleys were yet to be taken.
the lack of guitar heroes is a result of the obvious having been done, and done, and done, and done, and done, and done..........
lets face it, someone being slightly faster than the last shredder isn't all that exciting...... it was exciting the first time because it was innovative, but it's true power was in it's novelty...... if that weren’t true, we'd be hearing it a lot more still.
so.... guitar heroes gone, mostly. do i see a need for another 3 minute blues solo/tapping frenzy/tricky finger exercise/face scrunching cord bend?
yes, but only very occasionally, because it's currency has lessened so that it must actually make the song better, because it in and of it's self, is not all that interesting.
