After recently expanding the game with a free update with Nigeria and Chile, Dinosaur Polo Club have given users another reason to come back to their excellent strategy sim.
This update comes six years after the original release, so it seems good things come to those who wait. Adding in Steam Workshop support, you can now make your own maps and share them with everyone. They also crafted detailed instructions on how to actually get map-making, which doesn't seem to be too complicated. Everything is done through plain JSON files with no special tools needed.

As the developer mentioned in a previous update post, we can expect more to come for Mini Metro. This appears to be the major featured mentioned, so we're now waiting on another map expansion to come. Pretty amazing how they've supported it for this long - it must be continuing to sell well.
