Nitrous Roxide must be quivering in his boots!!!   Guitar Hero: On Tour has sold over 300,000 units on its first week, smashing the record eight fold.   It also puts it in Activision’s top 5 selling debut games of all time, on any platform, of any game.

When asked, Mike Griffith, president and CEO, Activision Publishing, said “Guitar Hero is one of the most successful entertainment properties and continues to push the boundaries of innovation with Guitar Hero: On Tour.”

I’m pretty surprised by this, and would love to hear what our readers who own the game have to say about it.
