Aspyr has informed us that the Rise and Fall expansion for Civ6 on Mac and Linux will be released REALLY soon (exact date is embargoed). It will not include the March 8 patch, so cross-platform multiplayer is still not available. Aspyr graciously provided CivFanatics with several free Steam activation codes for the expansion. Please post in this thread if you wish to request one of the codes. If demand exceeds supply I'll randomly select the lucky winners. The deadline for making such requests is one week from today, March 27. Please post if you have any questions. However, keep in mind that I'm not a user of either Mac or Linux (so I'll have to forward any technical questions to Aspyr).
