Nuts. My parents didn’t let us play with playing cards and instead used cards from other games. Fortunately they don’t have the same opinion anymore, and we play with playing cards all the time.
I don’t really understand that whole line of thinking. You can gamble with anything, so the medium isn’t going to encourage people to gamble. Instead, just teach kids what gambling is and why it’s bad instead of banning anything used to gamble.
I don’t let my kids play F2P games because they have the same draw gambling does. I let them play with face cards though, because why not?
