Lockpicking. It sounds useful in theory, but being locked out of something you need (e.g. your house or some container you’re authorized at work) pretty much never happens, and even if you are in this kind of scenario, there’s no shot you’re carrying tools on you 24/7. Still a pretty fun hobby though.
I personally use bottles installed through flatpak for non-steam game needs. Especially if you’re pirating, you can use flatseal to disable things like internet access for bottles (and games that you run through bottles) and inter-process communication, making it just a bit safer if you have trust issues.
Setting bottles up is a bit of a pain, but once you do that you can pretty much run anything through it easily
There are some setups that allow you to do this.
nixOS or nix + home-manager on some other distro, but it’s a high skill-floor way to manage a computer so wouldn’t recommend
window manager heavy setup where you just set it up then copy over the config files to the new install, a bit of a pain to first customize but viable if you’re willing to ditch mouse-heavy desktop experience in favor for keyboard and shortcut focus to control everything.
Apart from those two cases, not really.
