But even then, when everyone is trying out a new indie game there’s a chance it won’t work on non-Windows. It’s happened to me.
I'm far from an authority on this topic but from my understanding both Sony/MS have introduced mkb support, but so far it looks to be an opt-in kind of thing and it's still relatively new.
The problem is more the audience. Console players generally expect to be able to just connect the console to the TV, sit on the sofa and play with the official controller. That’s all the game are required to support to be published on the platform.
Even if you were willing to play at a desk, you’d be matchmaking into a special (and small) mouse pool on the console game. Anyone willing to go through so much faff will accept the extra annoyances of a PC, even with kernel anti cheat.
I am very pro-Linux and pro-privacy, and hope that the situation improves so I don’t have to continue to compromise.
