I had this game as a teenager, but isn't there a card for condom? I can't remember all the cards but that one stuck out. Maybe they don't have that anymore. I would maybe buy it and go through the cards and sort out the ones I didn't thing were appropriate.
It might be too hard a game for the 12 year old though, likely won't know some of the politicians etc... but it could be a learning experience for him/her.
