No disrespect, but it's pushing 4 buttons in a sequence. Sure it takes timing and coordination I suppose, but it's not musical skill. I like watching people play it especially when they are good at it, but I'm not going to try it.
I played guitar in a previous life(before marriage...fatherhood
) and it looks like it could screw with your actual mechanics since it has nothing to do with chords, scales, etc.
It's guitar playing the same as Mario Kart is racing.
It would be cool to see if someone could make a game that used a system where actual chords, strumming, runs could be tracked somehow. It would probably be crazy complicated to do, but it would make for a nice more realistic challenge.
Screw just learn to play!!!
Now if they would come out with Bassoon Hero or Tuba Hero.......
