Cities: Skylines is a city-building simulation game by Colossal Order. The game shares similarities with the well-known SimCity, City Life, and Cities XXL city building games. The player is responsible for maintaining the city’s population, health, happiness, employment, budget, pollution (air, water, and noise), traffic flow, and other elements. Cities: Skylines will not disappoint even the most hardcore city-building enthusiasts who are picky with their favorite genre. Another similar game and a good alternative to Cities: Skylines is Cities XXL which was also released in 2015.
