About the base game:

Cities: Skylines is a modern take on the classic city simulation. The game introduces new gameplay elements to realize the thrill and hardships of creating and maintaining a real city whilst expanding on some well-established tropes of the city building experience.

From the makers of the Cities in Motion franchise, the game boasts a fully realized transport system. It also includes the ability to mod the game to suit your play style as a fine counterbalance to the layered and challenging simulation. You’re only limited by your imagination, so take control and reach for the sky!
