I've got some friends on PC and some on Mac, however whilse some Mac friends have the steam version, most have the mac app store version.
Is there a way to play (Civ5, BNW) between these groups. Other questions didn't definitively answer this; I understand that we can't share a pitboss or play over the internet, but what about a local network? If the issue is steam DRM or clients, shouldn't local network lack that?
If a local network can work, could I set up a sort of "local internet"; spatially distanced players but we all access a closed infranet?
