I went down to vegas a week ago or so and I finally saw this DDR... I put my $1 in it and tried...of course I SUCKED at it and stuff... so I go back up to my hotel room and like an hour later or something I go back to the arcade to see these 8 year old girls playing it...they didn't miss a beat at all and such.
They played it like 3 hours (maybe longer I was only in the arcade for 3 hours) non stop everyone was just watching them, no one said anything just watched ...
