DDR 4EVER!
I have DDR Extreme and this is an AWESOME remix of it! I also have Dance Factory. You can put ANY SONG IN AND IT MAKES A DANCE TO IT! I put Ridley's theme (from Metroid Prime) and I got the workout of my freakin' life! It made it so awesomely! (But you need to put it on Normal Mode) If you don't have that game, YOU AREN"T A TRUE DDR FAN! GET IT!
