Very good point. Another issue, at least in my country, is planted forest. Of course it is better to plant forest than turning it into farmland but basically all forests in Sweden are planted and the planted forest is cut down with 70-80 years interval. The planted forest is less diverse than an untouched forest would be and it is hurting the wildlife during the first years after being cut down.

Arc Raiders is playable in Linux, it got gold in protondb.

Path of Exile also got gold and PoE2 is platinum.

R.E.P.O is platinum.

That should make more than half of the top 10 games compatible in Linux. Unless it needs to be native for compatible, but I don’t have a problem with proton as long as it’s enough to select the latest proton version to be able to play.
