PayPalCivilization VI was recently updated to give Windows and Mac players cross-platform multiplayer, sadly the Linux version was left out. We spoke to Aspyr to confirm what's happening.
It's not just cross-platform multiplayer that we're missing, as the Linux version hasn't recieved the Spring 2018 Update yet which was released for Windows back in May. Sadly, this type of wait has become common when a third party ports a game to Linux and it's understandably hard for some to have to wait—especially if it's a game you're particularly fond of and one that can be enjoyed in a multiplayer environment.
The good news, is that Aspyr Media are obviously well aware of this. Here's what they told us today:
We are very close to getting both the update and cross platform play out on Linux. If all goes well, we should see both in the next couple of weeks.

Wow
wow
this is huge.
Now I'll be able to play with my windows friends :D Thanks Aspyr, I had basically given up hope on this one! And I didn't see it coming...
However, does anyone know about this redshell thing and how it affects the Linux port? link It dosn't sound particularly malicious but the game is getting review bombed over it.

Thanks! I just read in the latest patch notes that redshell was removed from the windows version too, which is cool I guess.

Apparently a rash of negative reviews is an effective clue-hammer. :-p
Regarding the cross-platform multi-player, I got the impression it did in fact require changes in the Windows build as well; fortunately, Firaxis seems to take patches/feedback from Aspyr, rather than just handing off the code and completely washing their hands of it.

I know that there are other multiplayer design patterns that indeed do require client side floating point math to perfectly match server side calculations, but afaik those are mainly used in real time strategy, as there the client needs immediate feedback and expects to see correct results. As the Civ VI developers seem to have taken such an approach, I'd be really curious what their reasons were.
