After Activision acquired Red Octane and its Guitar Hero franchise, developer Harmonix didn't trip over. As a comeback, they're dishing out Rock Band with more instruments than their previous games.

So what does Activision think of this? They just said,  "[It] wasn't surprising that [Guitar Hero] has attracted imitators." In short, they're calling Harmonix and its Rock Band title a Guitar Hero copycat.

As if that wasn't enough, Activision gave themselves a pat on the back by boasting 200,000 Guitar Hero II song packs sold on XBLM.

They are also quite confident that Harmonix' new title won't hurt Guitar Hero, claiming they have a competitive advantage thanks to significant brand recognition.

Guess what? Harmonix created Guitar Hero and those song packs - the same song packs and the first Guitar Hero that spurred the franchise to stardom. Seriously.
