Oh, for the sake of… sigh
Please get that idea out of your head that supporting Linux (in case of distributing games on Steam, specifically) means having to support anything except Ubuntu.
Now, if you think that supporting even one Linux distro is still too much trouble, fine, but please stop spreading those claims that are only shared by those looking for excuses.
That’s really not my experience, and I’m watching (and/or participate) in a number of Linux communities.
People on, for example, Arch know very well that IF a game developer will support Linux, it will in all likelyhood be specifically Ubuntu and that the dev cannot be expected to have machines or even VMs to test on all the distros. They’ll still report bugs, sure, but that’s just something Linux users seem to be more keen on doing.
You don’t land on something like Arch or SUSE by accident ;)
Actually, users there even seem to be rather keen on finding workarounds to “make” Ubuntu releases work for them just as well.
Which as a Linux user myself, would just be way too much trouble. But I guess Arch users are the kings of tinkering amongst the group of tinkerers.
The “demands” I’ve seen from Linux users are usually the likes of “no tux, no bux” (which makes sense, really, if you don’t support my platform, I won’t likely buy your game) or “fix this Linux bug” (for example, Pathfinder: Kingmaker released with save games not working on any Linux, and quickly fixed that).
If those seem outrageous demands to anyone, then I don’t know what they expect. There’s no difference between those demands and demanding a release on Switch - other than the likelihood of being heard, that is.
