A bit about the game from the Steam page:
Build your empire with one of six unique factions, ranging from the militant Vanguard to the dinosaur-riding Amazons and the cyborg-zombies of the Assembly. Progress through each faction’s missions using your wits, military strength and diplomacy, exploring planetary ruins and encountering other survivors as you unravel the history of a shattered civilization. Fight, build, negotiate and technologically advance your way to utopia in a deep single player campaign, on random skirmish maps, and against friends in multiplayer.
I kind of lost hope that they would ever release a Mac version. Paradox had put up a Mac Apple symbol on their site before the release of the game, way back in August 2019 but then that was "corrected" and ever since Paradox (publisher) and Triumph Studios (developer) have been dead silent when it came to if there would be a Mac version.
With the release of the Age of Wonders: Planetfall Invasions expansion they quietly announced the release of the Mac version.
I was pleasantly surprised when I came across the Mac symbol today when looking through my wishlist so I bought it and am downloading it now.
So if you are interested it's on Steam for 50% off:
I'm sure it will be on the MacGameStore at some point, but right now it's 60% off on the WinGameStore (steam key):
