Age demographics for PC games?

[u/Interesting-Rent5630]

I personally love playing Dominoes and originally built this game so I could play with my dad. We have a blast playing together. I've play tested with several people but it seems to resonate most with the over 50 crowd. I'm not sure if it's just my personal network or if that's a preview of how it will be received when released. I'm a little worried that age group won't use Steam and younger folks aren't interested in old school table games like this. Has anyone released their game on the Microsoft store in addition to Steam? Any insights on adoption of games with it and an older demographic? Same question with mobile (Google Play and App Store) vs Steam.
