Players have personal cards that show what they can build, and should discuss and plan with the other players how to best develop the city. At the start of each milestone, one connected land board is chosen, bought, and flipped over from its nature side to its developed side. The goal is to finish a number of milestones while keeping the inhabitants of your city happy. Gameplay starts with four land boards being visible, though this varies depending on the scenario. Cities: Skylines – The Board Game is a co-operative game based on the popular computer game of the same name by Paradox Interactive.
