Another year, another Just Dance. Only this time it's a little different. Of course there's the base element of dancing, but Just Dance 2015 takes things to a whole new level. Presumably after purchasing the original game, a free app becomes available on your smart phone which allows you to join in the game just by holding your phone! There is seemingly no limit to how many people can join in, with numbers like 20k being thrown around with the possiblity of stadiums full of fans dancing around to the same song.
Essentially it looks like a lot of fun, if you like dancing of course.
