I deleted my only copy of Windows and reinstalled OpenBSD on my big PC. It's way better in almost every respect but I miss video games lol. I'll probably install Linux somewhere and boot that to play video games eventually but games on your native operating system are pretty convenient
Edit: thanks for all your recs, I am crashing from caffeine rn and have to log off lol, will check them all later
Mindustry is great, I honestly don't think it has that big of a learning curve if you play the campaign. Each level introduces a minimal amount of new mechanics.
Mindustry also runs on mobile
I loved mindistry, I played it obsessively for a month or so last year, 10/10
