To expand a little bit to your comparison, keep in mind that giving such root access and actually putting it to X or Y use are two different scenarios. That’s probably why LoL anti-cheat doesn’t work on Linux even if you were to run it as root. But, again, I’m quite ignorant on that technology too. Needles to say, there are games with anti-cheat technology that work on Linux (e.g. Steam VAC)
