Published by Paradox Interactive on the Steam platform in March 2015, Cities:Skylines is a game that advances an earlier simulation experience, Cities In Motion. It combines extensive urbanplanning tools, architectural and civil engineering abilities, along with the capacity for usergenerated modules – ‘modding’. The result is that the single player can operate like a developer on steroids, advancing rapidly from a starting position game of a 2km square plot at an exit on the freeway/motorway/autobahn. Broad acclaim has been mildly tempered by concern that the simulation doesn’t impose random acts of disaster.
