To expand on this and provide some examples, I've recently played Wuthering Waves, Tower of Fantasy, The First Descendant, Phantasy Star Online 2, Black Desert, Lost Ark, Throne & Liberty, probably others I'm forgetting, all of which contain anti-cheat of some variety and all on Linux.

There are some that don't support Linux and likely never will like Valorant or Call of Duty, and even fewer that dropped Linux support like Apex Legends.

Mostly mobile ported gacha and Korean MMOs. It's good that it runs on Linux for you, but most people don't play these games. Most people are interested exactly in the ones you've listed as not supported.
