the only game with the ability to be gay and not gay at the same time!
"osu! is something essentially better then tap tap. It's some weird beat game with a lot of kwaii desu stuff in it. It will question your manliness on whether you are the beat master or not. There is plenty of songs to choose from and an odd mix of user made ones." - Block Box
Basically its dance dance revolution/audiosurf mixed in, it uses the mouse instead of keyboards or stupid stuff, it has some Multiplayer in it, lots of fun alone or with friends.
