Maybe skating could be the gameplay element for a "Teens Room" stuff pack. I think the gurus are well aware that the teen life stage needs a bit of fleshing out and while a SP won't solve that entirely similarly to Kids Room Stuff, it definitely will put a band-aid on it.
So skateboards & roller skates as gameplay objects, with posters, mp3 players etc as 'stuff'. I don't know, I can't really think of more teen-specific items for some reason haha and I'm not too far gone from the life stage myself. I doubt the game's rating would allow for many of the other elements of a teen's life.
