Can I just go to gog.com, download The Witcher 3, click on the installer and have it install? Or do I have to configure some bullshit that's beyond the capabilities of the regular user before I can do that? You seem to be completely disconnected from real people. Real people also don't care about what kernel anticheat does and just want it to work.
I have played a game from GOG on Linux (Icewind Dale), it had Linux download, I opened it and the game played 100%, even multiplayer with non-Linux users.
It doesn't. But congratulations on showing that Linux gaming outside of Steam is at exactly the same stage as it was years ago: Most titles don't work.
Again with this. You can look up the solution, I can look up the solution. Mr. Regular Joe who just got off an 8 hour shift and just wants to play games for an hour doesn't know or care to know what Wine or Lutris are. You need to get out of your bubble.
