Card Hunter is an excellent trpg/ deck builder that has card based actions. Excellent single player with multilayer options that I haven’t explored much because I generally need to be able to pause for extended periods, but it seems solid enough (no idea if there is an active community though).
You can pay to skip ahead, but I had a great time never paying for anything. Probably put 100 hrs plus in.
On Android just use Brave browser and turn on the setting to allow tabs to play media in the background. Opera does the same thing.
Not sure what iOS options there are.
It’s by far the best mobile browser that let’s you run tampermonkey and uBlock on Android and it’s not close. I haven’t found an add-on that let’s me run video/audio in the background, so until then Brave stays installed so that running YouTube with no ads and the phone locked is an option.
Aside from that, Firefox gives fantastic customization options, runs well, and is less vulnerable to attacks specifically because it has a smaller market share and it makes more sense to target Chromium based browsers.
This is the perfect kind of thing to add to your game. Minimal effort on your part, players love it, and they’ll come up with something awesome you can run with later.

Disco Elysium is the game that instantly came to mind. Basically all story that is brilliantly written with incredible voice acting. I hope OP checks it out.
