Has anyone purchased this game yet and if so, do you think it is safe to play it on a hard surface? My significant other wants DDR Hottest Party for Xmas, but I am concerned that the pad may slip all over the place on her hardwood floors. With her appendix and broken toe, I have already taken her to the hospital twice this year. 
Also, I have only played one of these games once, so I don't know much about it. How does this game compare to previous incarnations?
Sorry if this has been spelled out in another thread. I unsuccessfully searched around before creating this thread.
Thanks
