Wayland has a mouse capture bug in proton / wine. It particularly seems to be an issue in FPS games. That may contributing to slower adoption for Linux gamers.
KDE Plasma 6 made it to Arch about a week before Tumbleweed. Tumbleweed is also still using Xorg by default for Plasma 6. That said both had it in their repos withing 2 weeks of release. Is there some history here for Gnome on Arch?
I don’t know. As a fan of the genre there seems to be renewed interest from some very grass roots developers. I would have agreed with your take in 2020, but in 2023 we have announcements of:
the Riot MMO
Ashes of Creation
The Ghost studios MMO
These are all still in development, some still in the very early stages. But I would say there appears to be renewed interest in the genre by developers. These projects are major investments by industry veterans. There is more hope for a major new game.now than there has been in the last decade.
