I dont know, but stepmania is a very large simulation that works with Dance Dance Revolution products.. also I do not believe legality issues would be a problem because DDR is not a patented idea [that is dancing to music] which explains why there is other dancing games from other companies such as DWI and Beatmania... but who knows, I guess Stepmania has not become as widespread is I believe it is.
If you want to learn more about SM and simfiles and about all of it go to

As for the second post that sounds good

I just broke up with my girlfriend because her parents are hard ***'s and wouldnt ever let me take her places. But I am not very talkative which might make it hard for me to meet people at a convention -[then again you never know, since I havent been to one]-
I am gonna ask my friend if he'll go when I get home...
