Cities: Skylines (2015)

A jammed junction can stop services reaching the same neighbourhood that caused the traffic. Looking at routes, road connections and public transport gives you a way to work on the cause rather than repeatedly adding lanes. The base game's usual starting point is a new town, so this is chiefly about untangling your own growing city; specific rescue scenarios can depend on expansions or shared maps. Choose it for watching a redesigned network change how the whole place works.
