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?
It's like tapping out the beat to a song while listening to it except with a cool controller/interface and a progression system. The most difficult songs in Bemani games are as difficult as playing a real instrument (or the same as playing a real instrument in the case of Drummania).
