@gamingonlinux @lutris I mean, games like Minetest, Minecraft, Veloren etc. have anticheat measures as well. I would know because I have literally worked on improving Minetest anticheat code as well as having made a cheat client for Minetest.

In general I'd agree that games that have centralized infrastructure and don't allow you to set up your own servers usually do not have opportunities for ethical cheating.
