You dont need to liike or be good at dancing to have fun with this game.
The sound comes through really clear, and is very entertaining, although coming from Japan or wherever it comes from, it doesn't have many(if any) good songs. You will be dancing to songs you don't know and probably will never know. And unfortunately, after doing each song over and over again, it gets very repetitive, but never less fun. However, this game can be a real hole in your pocket, you have to buy the game, the pads, and for multiplayer up to four, four pads and if not already owned, four controllers. It would be a little better if it came with pads like twister moves, but alas, it doesnt. So, if you don't have about 200 dollars for this game, and if you want the best stuff, up to 2000 dollars, then you shouldnt have it for multiplayer.
All in All, its well worth it, but can be very costly, think before you buy.
