After you've been on Listia awhile you can set what's called a GIN on your auctions, which stands for 'get it now'. That way if someone doesn't want to wait for the auction to end, they can get the item right away. Listia charges credits for using the GIN option, so it does have a drawback.
It's not a copy the steps type of game. You basically are dancing to the music tracks of game with the remote. I have never played it but I assume the remote movement is displayed on tv as you move.
