Like, it used to be one of the biggest franchises. Fucking everyone had some of those games. You couldn't go to a house without seeing a plastic guitar. It was a fun little game that encouraged hanging out together and you even got to listen to songs you like. Then it just kinda died overnight. How did they do that?
Harmonix made the first two Guitar Hero games then sold the rights or something. They went on to make Rock Band which took over a lot of the popularity.
