Activision announced this morning that Guitar Hero: On Tour is booking gigs all over and has sold 300,000 units in its first week. The publisher states that GH:OT is the company's best launch on the DS by a factor of eight; not only that, but it's also one of the top five best-selling launches "in the company's history."
Activision's Mike Griffith -- who's probably still high from his $1.5 million bonus -- is excited about GH:OT's "breakthrough peripheral" bringing the Guitar Hero experience to the potential 41 million DS owners in NA and Europe. All we know is we'll have entered a strange new world if we start seeing people playing this game on public transportation.
