You’re definitely pointing real things, but it may not be as simple as you think making a game as large and as complete as Fortnite. Also, the point of 33M users is kind of moot imo, because the vast majority of those people won’t even install steam on their computer, just like there may be a billion Microsoft computers and only a fraction has steam installed. It is also pretty clear that valve will not help Epic make fornite more compatible on their platform, as they are a direct competitor. I am not saying fortnite wouldn’t work, I am saying they do not want to assume the maintenance burden of making such a large game run on an compatibility layer, because when shit doesn’t work, the blame goes to them and not the layer. And that’s bad PR
