Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

I'm not sure what a good written guide for manually running linux games is off the top of my head, but generally yeah you install Lutris, install the latest Proton-GE version through e.g. ProtonUp-QT, create a game entry in Lutris with a "Prefix" location dedicated to your wine prefix, pick Proton-GE as the runner, copy the game into the generated prefix, target the normal EXE, and launch it. Sometimes if a game isn't launching you'll need to use "winetricks" to install vcrun2022 and dotnet48 dependencies into the wine prefix, since each Wine prefix is sort of like a copy of windows, and windows has a handful of dependencies that games sometimes rely on. I've heard you can also just add the game as a "non-steam game" to steam, but I've not bothered as Lutris gives more control. Again I can't vouch for any specific guides, but the keywords from this post should help target a general direction to move in.
