Add the games executeable as non steam game

Iirc you can install games or apps from an .exe installer using lutris. You can check !linuxcracksupport@lemmy.world for help with pirating games with Linux.

Am not the pirate that I used to be, but I’ve found that they pretty much work. Cracks seem fine, repacks make a couple of assumptions that tend not to be true on Wine:

• how folders are arranged

• leaving out all the additional installers for things like .net, because obviously everyone already has them

I’d usually make a new folder for ‘what you’re installing’, create a new launcher for it in Lutris selecting that folder as the base directory, and then use the ‘run different executable’ option in Lutris to start the installer. Once that completes, you should be able to adjust the config to what you’ve installed, see if it works. Be prepared to try lots of additional installations with WineTricks, particularly .net and directx.

(To be fair, a lot of legit older games need the same in order to work, if you’re installing from CD / DVD and things.)

You should technically be able to run the exe with proton (assuming, you’re talking about Windows games). Maybe Steam does some extra work like setting certain environment variables (see https://github.com/ValveSoftware/Proton#runtime-config-options for a list).

Or you could just run non-steam games through Steam
