A few weeks ago there was this article posted here about why some game companies are trying so hard to kill their old video games and give 0 shits about preservation (as in delisting them from stores, not selling them anymore, etc.).

One of the answers given by the publishers in the article basically boils down to “old, preserved games would compete with the newer ones and eat into their sales”, which does say quite a lot - they don’t care about losing sales of older video games, all that matters is the sales of the newer ones, preservation be damned.

There’s torrminator for once, it has a section for linux cracks specifically. There’s also a large collection on the internet archive of native linux games that you’d have to find for yourself (to keep in line with the rules), but it shouldn’t be too difficult.

I personally use bottles via flatpak and flatseal to make the games not connect to the internet when it’s not needed just in case.

If you want native linux games, there are sites for that.
