Though it may not be the most known, this Bemani (Konami's music simulation series) feature has you dancing to high speed *most of the time* music and watching coloured arrows travel up the screen.
Gameplay is simple: Step on the appropriate arrow on a dance pad as soon as it has hit the top of the screen.
There are two types of DDR. Dance Dance Revolution, and Dance Dance Revolution Solo. With most of the DDR games, you only use four pads (which resemble a plus sign). As for solo DDR games, you use the four on opposite sides plus two corner buttons in the top-left and top-right corners.
DDR also comes in many different mixes, which include different interfaces and song lists.
"Wow what's that awesome possum dancing game thing over there in the corner of the arcade called?"
"That would have to be Dance Dance Revolution... yeah that's DDR!"
"Holy crap, let's go play! I hear that MAXX UNLIMITED and PARANOiA are easy songs! Well, at least from some creepy girl named MJ."
the religion in which one strives to be as awesome as the mythical Bradmonkey The greatest being in existence through prayer meditation and chanting of the great 5 words "i want an elephant now" noone nows exactly what these words mean but all we know is that they invoke the power of W00T the almighty power to grant awesomeness.
