It's utterly amazing how many people seem to equate playing Guitar hero or Rock Band with playing real instruments, or at least assume that other people do.
Here's a news flash to everyone: PLAYING GUITAR HERO IS NOT THE SAME AS PLAYING A REAL GUITAR.
This is comparing Apples to Sauerkraut, and should be regarded as such by more people.
There is no need for people to start playing "real" instruments instead of Guitar Hero because there is some worldwide deficit of bands. There is no need to make such a stupid statement claiming thus.
I like Rock Band because it's a rhythm game with a unique control interface. During social gatherings it is a good draw to get people together because you are working toward a common goal, unlike other social games like Raving Rabbids, or Mario Party. It is entertainment.
Generally one starts a band for one of two reasons: You have the desperate need for an outlet for your musical creativity, or you want to make money. Nickelback, of course, fall in the latter category as evidenced by people's ability to mashup two of their songs and they synchronize unsettlingly well (Do a search for "How You Remind Me of Someday".)
So, please. Stop this petty squabbling of "I'm better'n you" because you either play a real guitar instead of "wasting your time" working to get 5 stars on Expert mode; or because you can ace "Between The Fire and the Flames".
Musical rhythm games are like Karaoke.
You never hear any modern dance choreographers bitching about people playing Dance Dance Revolution, do you?
I would bet the true impetus for this idiot statement is that Rock Band and Guitar Hero have introduced people to some of the highest quality rock music available, many of which the general public probably haven't been exposed to, and they are realizing that by being fans of corporate success story bands like Nickelback and other Top 40 "Pop Rock" stars they dove right past the cream of the crop to scrape the bottom of the talent barrel to get their music.
