I would recommend anyone to play competitive multiplayer games on Linux.

Competitive games, and specifically CS, has been my go-to for about 10 years (I am still shit tho). As you say, Valve will most likely not put anti-cheat that won’t work on Linux in it. But if they would do that, I would just not be playing CS anymore.

I play what I like, and if they would make the stupid choice to break it for my machine I guess they just don’t want me playing it any more. In that event, I guess I’ll just have to find something else to play.
