Dance, Dance

If you've been to an arcade in the last 3 months you've seen this dancing game. The premise of it is that you have to hit the certain steps in time with the song. The game tells you when and you have to be coordinated.
Well... we go this for X-Box for Christmas and it is a riot. It has the be the ultimate party game. Just watching people gyrate and nearly fall down is worth the price of admission. My brother dancing was hilarious and his kids were funny to. You sweat when you play video games and you can embarrass yourself in the privacy of you own home.
Also for a fun treat, try playing Tetris with the foot pad.
