This would be great if it was viable. In fact, multiplayer gaming has always been the only thing preventing me from ditching Windows for good since the mid 2000s, and I’m still waiting. There are just simply quite a lot of people whose priorities aren’t necessarily ‘open source first, everything after’, but would love to switch to Linux if their other (higher) priorities allowed it. It’s not just kids (or gamers - I’m looking at you, niche enterprise solutions).
