I do play Guitar and i have for nearly 20 years now (off and on).

I love guitar hero absolutely love it. However you should take it for what it is: a Game.

Its not an emulation of the real thing it does not play like the real thing it wont makke you learn the real thing either (even though i heard differently for the drum set of rock band). the plastic guitar is a controler just like anyother one shaped as a guitar.

But It a lot of fun!
