My parents, my brother and I would play cards while we ate dinner. Euchre, Sheepshead, Uno, Hearts, Oh Hell (aka Up and down the River), and some others. Heck, we even pulled out the Parchisi board!
Fortunately, my wife's family did the same thing. Now, our four adult kids and significant others (none married, yet) will come over and say, "Hey, can we play cards?" It is something I'm not taking for granted.
That said, my Dad smoked like a chimney. I don't recall them playing cards and us being nearby. I think it is because they didn't want the kiddos around while they drank. Yeah... that's it.
When I ask my 19-year-old son how many card games his buddies know, his response is typically, "not much... maybe War?" A lot of kids, like you alluded to, would rather play Video games.
