Mini Metro is a really simple Urban Transportation Planning Game that requires the player to think strategically about how to move people through the urban space most efficiently. Random stations that represents different areas will pop-out (e.g. Town Centres, Commercial Areas, Residential Areas, Universities), and it really requires the player to think about the dynamic demographics and different demands in transportation that these stations presents. It is a good game for relaxing and a good way to learn the dynamics and population flow of an urban area.
It is available on both iOS and PC (via Steam)!
