Rutracker has a category for Linux native games

Fitgirl repacks is your best bet. They do amazing work.

Be sure to always use the original, trusted link : https://fitgirl-repacks.site/

As a Linux user who lost at least 100 hours of his life wasting time trying to install a thousand different repacks, I suggest you to stay as far away as possible from any windows repack such as Dodi or FitGirl, usually they open but half way through the installation for x or y reason the installation stops and gets corrupted, you can try a thousand times with a thousand different commands and variables and nothing changes.

I suggest you to use "pre-installed" formats, Steamrip is my top 1 page to go to when I want a pirate game on Linux using Wine, and this is because the game already comes pre-installed, you just have to unzip the file and you have it ready to play.

Then, other highly recommended sites are Elamigos and GoG-Games, and if you really want to download repacks you have Torrrminator which personally I have never used.

Someone should create a community about Linux piracy like r/linuxcracksupport, I would do it but I don't know if I have the time and patience to be the mod of a community.

LinuxRulez is what I swear by.

I've run both fitgirl and dodi windows repacks on Linux, it's easy. Install protonUp-Qt and add proton-ge. Add the package installer to steam and run with proton-ge. Then run the game .exe with proton-ge once installed. If the game needs any dependencies add them using proton tricks. Also if you're running the game installer on a steam deck make sure you press the limit to 2gb of ram option.

If you're downloading games on 1337x go with Dodi and Fitgirl. They are the most reliable options. Their original sites are the best choice tho.

I'm playing through Far Cry 6, Hogwarts Legacy and Tiny Tina's Wonderlands on the Deck from repacks rn and I'm having no issues.
