Apart from the problem of my friends sticking with the same games I play regardless of my decision, the other problem is... yes, most people usually play the games that most people play. I also happen to be in that (high) percentage, so there's not much room.

BTW I've been playing League for a long time, and while cheaters have been a thing for a while, in my experience it practically became a nonexistent problem recently. It doesn't prove anything, just saying that League isn't in the 'cheaters all over' category anymore (imho).

Thankfully, Rocket League is actually pretty decent in this regard, so that's a "safe" one - but there's several more that still necessitates Windows, so I don't see the point of going back and forth in dual boot every time I switch games.
