The addendum requires the basic version of Cities: Skylines.
Inhabit a world where you define the rules. Cities: Skylines invites you to create the city of your dreams in a sprawling landscape dominated by cloud hugging structures and jaw dropping architectural marvels. Developed by Colossal Order, Cities: Skylines offers a vast backdrop and maps with endless sandbox gameplay and new ways to expand your city. Key to progression is the ability to influence your city's policy by incorporating taxation into districts. All this including the ability to mod the game to suit your play style makes this the definitive city building simulation. You're only limited by your imagination, so take control and reach for the sky!
