i would imagine eac on linux will have to be addressed once steam machines drop, but for now i look at it like, if a game requires eac, at this point the game studio is just too lazy or cheap [0] to be linux compatible so we just play something else. far too many great games.
[0] its even more silly considering eac doesnt seem to stop cheaters at all. every single popular game that requires eac is still absolutely overflowing with more than obvious cheaters.
Or a game example: I have Minecraft (Bedrock) on my phone so therefore I should be able to do the same things as Minecraft (Java) on Windows. The problem is they're the same names for different software with similar, but not the same, functionality.
