Yes it’s absolutely worth getting in to video games, there is huge breadth and choice on what to play, and a huge vibrant community.
Starting place is really what devices do you have? Do you have a laptop or PC? If so the world is your oyster and you will find plenty to play even if it’s not very powerful.
If you want something popular, cosy and accessible I’d recommend Stardew Valley. It’s cheap for such a great game, plenty of content, great learning curve and a huge wholesome community.
But there is loads of choice - you could play card games or puzzle games on you other devices and explore what’s available. PC games offer much more variety and depth compared to a mobile, and is very easy to access - no need to buy a console or hardware.
I have a mini PC running linux and I use it for streaming (including a Jellyfin library) and gaming. I love it and use it almost exclusively. However I have not gone down the rabbit hole of HDR and Dolby Vision for 4K DRM content.
I have a Google TV stick for that content, which is very far from ideal, I know. But in fairness I find myself barely ever using it.
If 4K and Dolby is important, I saw someone else recommending an Apple TV box as you can easily disable telemetry and the device isn’t riddled with advertising or tracking, but then the apps you download would still be a law until themselves. But probably way better than Roku, Amazon and Google et al?
