There’s tons of youtube videos / tutorials on how to create a live usb of a distro, such as linux mint. This will allow you to boot into linux and play around without installing anything and get a feel for linux. It’s nowhere as tech wizardry as you think.

And if all your games are on steam and don’t have anti cheat things, they’ll probably just all work with proton (linux compatibility tool in steam).

Local gardening stores often carry ladybugs. I just bought some yesterday when buying some topsoil. The true value hardware store near me also stocks ladybugs.
