I know that when Guitar Hero became a runaway hit, instead of going, "hey, we have a lot of experience in this space, how can we come in next year and clean the fuck up?" they went "what patents do we have that we can use to litigate?" Then, they found out they didn't have any. Then, Guitar Hero and Rock Band took over the fucking world. And Konami was left holding their dick in their hands. And their dick only had three buttons.
This is from a company with working guitar/bass/drum sessions since 2000, and licensed tracks since 2001.
