A few years ago, I would have said that any game that uses such a level of anticheat that makes wine/proton unable to play it (ie: kernel level anticheat) is basically malware and you _shouldn't_ play it anyway, out of both principle, and also because if they had a bug in their code, you're just opening up your device to an unnecessary privilege escalation vector that other malware can abuse to escalate their privileges. (This is not theoretical, this has happened before, eg: with Genshin. Though I believe just the mere existence of a signed driver was enough, since malware can just "Bring your own Driver" (BYOD) and download the driver, at least before it was revoked)
Now, I still hold this belief in most regards. But I do see the appeal, especially if your friends and peers are gamers and actively play these sorts of games, and you feel that you're missing out on socialising or making new friends in that aspect. But there are plenty of other games and consoles, if you could just convince them to switch...
This sort of anticheat exists because cheat developers ruin the experience for players, and for games that intend to be competitive in a real sense, the integrity of the game. Cheat developers keep getting smarter, so anticheat developers need to do the same. I guess the kernel is sorta as deep as you can go, at least with software.
I don't like it personally but I do understand why they do it. It just means I can't play those games on Linux, and some studios just don't care.
It's a shame that they don't care, though supporting such a minuscule percentage of the gaming market doesn't make a lot of sense unless out of principle/just do to it.
