For the mods at least, the dev interview at PAX clearly had a moment when one guy said "the possibilities of combination with civilizations switching is going to be higher, especially with the modding community adding custom civs.
But since they said a huge part of the playerbase is console, I’m guessing mods won’t be using the steam workshop but the launcher so that consoles can have mods…
As for Linux support yeah I would like to hope, maybe the stats of Civ6 on the steamdeck could push them to make it compatible but if they have denuvo I doubt it…
Also noted :
It’s still on and will close at the end of the month. But yes I’m very annoyed that they didn’t share much of the instance outside a small notification on the admin.ch website. But the goal of this whole pilot test is that if Mastodon became big within the year, they would already have an instance running with officials accounts. But instead I guess they will focus on Bluesky.
