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?
Well of course, which is also what sunk the thing. No one brought up shot like DJ Hero and Tony Hawk Ride and the oversaturated peripheral game market at the time. The Wii also helped destroy that by having most peripheral gimmicky stuff be part of motion control. I hadn't really thought of it in about fifteen years but the guitar hero craze almost certainly influenced the design direction Nintendo took with the Wii
Also for drums once you get enough peripherals it's just a regular electronic drum kit. Which are neat and cool and I'm looking into one.
