My gen-x ass plays games with my millennial wife and gen-z kid. Sometimes, my mom plays too, so add a technical baby boomer to the mix. Technical because she came in at the tail end of it; they’re sometimes called generation Jones or some other weird shit.
Hell, My grandmother tried playing some games with the kids of the family back in the original Nintendo days. Didn’t quite have the patience for Mario and such, but she put in some effort just to understand. My grandfather wrecked us at duck hunt though. Only game he would play, but the guy was a competitive shooter, and his skill translated to the game well.
Having fun with people you love is just goodness. Board games, video games, card games, ttrpgames, whatever it is, try and be open to things, and you’ll have fun together.
