From my experience, I can install several repack without any issues on my Mint install (using wine). If you overwhelmed, the easiest way is to add the .exe of your game as non-steam game through the steam and the proton will handle the rest assuming you won't find dependency issues, if you stumble across problem try to search protondb for solution.

Personally I run my games with wine because I couldn't figure out how to make use of bottles and lutris (ye I'm weird).

EDIT: Also you can run your modded games on Linux, so far I have tried modded nfs mw (2005) with hard+, underground2, and new vegas, they are works like on Windows.

If shit happen, rtfm. gl op on your journey!

nope

Some repacks (fitgirl and dodi and sometimes others) occasionally decide not to install ever in any linux system with wine or proton (they’ll crash at some point in the installation), and then you’ll have to install them first in a windows vm and then move them over to linux. It’s not really a rare issue, like 50/50, depends on the repack and its compression settings and just the luck of the day. Games that are already installed which you’re just moving over work perfectly 99% of the time. I recommend lutris.

It’s never been difficult for me to run pirated games on Linux. Occasionally you’ll get a game that needs something like the .NET framework, which increases the install time by about another thirty seconds or so.

Lutris and steam's proton (with protontricks if needed) have worked for me quite well so far. Biggest possible issue is with the different dependencies that games might have (I'm looking at you .NET)

Not at all, I have been running Linux for years now without any issues. Lutris and Heroic Launcher covers all my pirated gaming needs.

Linuxrulez is nice, for ones that are still seeded at least. I have over 300 games that run perfectly on EndeavorOS and Lutris, wine is literally magic.

Jc141 has a lot of pretty good releases for Linux.

It'll be easier than running uncracked games. It's difficult to say how well your games will run in general.

Its not as easy as launching from steam for example, but if you have some basic linux knowledge and the ability to use Google you can get 99% of pirated games running in either bottles or lutris. Search for steam deck specific piracy guides, they largely apply to all linux distros.
