Like other posts, Factorio. You will lose sleep. Set timers…
Proton and Vulkan make most things easy-ish if you are using Steam. Note that there is a little properties button on the game page that you probably need to use to force it to use Proton so it will install. Proton DB is your friend. Lutris + Wine is pretty good too. Proton is just Wine with enhancements.
You may find Helldivers a lot of fun too, especially if you can play with friends. It is suitably ridiculous in the best way and is sort of human vs aliens/robots. All of the humans (us) play on co-op teams to bring Democracy to the universe. There is a game master from the company that makes it that is leading the war against us. Like I said, suitably ridiculous. Most of my friends are playing it nightly and it will be a big part of our LAN party this weekend.
