My favorites are Katamari, guitar hero, rock band, DDR, and Boom Boom Rocket..

They need to make a guitar hero type game where you can use ANY midi instrument as a controller, think about it there are electric violins, piano, saxophone, flutes, ANYTHING and if it actually played whatever note you play instead of a generic fail sound when you screw up, and used an actual music staff it would be the PERFECT for learning to play real actual music. If anyone decides to do this you guys are my witnesses I was the first one to make it public lol just kidding I don't have any fancy lawyers or anything. IP is for the wealthy amirite?
