Think of the original Guitar Hero, and two names pop immediately to mind: Harmonix and Red Octane. A third name that you might not be aware of: Mad Catz. Speaking to Kotaku, Mad Catz CEO Darren Richardson has revealed that peripheral maker was originally part of the Guitar Hero project. Mad Catz was responsible for the Xbox version, but eventually decided to pull out of the project thanks to a lawsuit filed by Konami -- which resulted in Guitar Hero being exclusive to PS2.
Furthermore, Mad Catz actually paid $300,000 to remove itself from the project, only to see it grow into the gigantic success it is today. Says Richardson, "Everyone else made hundreds of millions and we paid money to not be a part of it." Ouch.
