Ostriv is a game I've not heard anything about for quite some time, after initially covering it here on GamingOnLinux back in 2017. It's heading to Steam Early Access this year!
Ostriv aims to raise the bar of city-building experience by adding a huge amount of possibilities and removing annoying limitations. It allows for truly organic town layouts without the grid and angle restrictions on a three-dimensional landscape. The goal is to make player's creations to become alive and believable communities where real-life problems would arise, thus making the late game a new challenge rather than a repetitive chore.
The game was already stated to be coming to Linux years ago, however it's good to see this continue to be confirmed as development pushes ahead towards a release. As stated on the Steam page (if you expand the Early Access info box), Linux support is set on their roadmap with Mac only being a "Maybe".
Currently, the developer is planning to enter Early Access sometime in Q4 2019, with the Linux version due later when more of the core gameplay is implemented. Will let you know when they have a solid date in place for the Linux version to be available.
You can follow/wishlist it on Steam, looks like one to keep an eye on.
