Cities: Skylines is a PC city-building simulation where you design and manage a city—laying roads, building power plants and water systems, managing traffic, and keeping citizens happy (by adding parks, schools, and hospitals). For PC players who’ve built massive metropolises, what’s the most challenging part of city management—Was it fixing traffic jams (e.g., adding highways, roundabouts, or public transit), balancing the budget (avoiding debt while expanding services), or handling disasters (like floods, fires, or riots)? How did you plan your city’s layout—Did you use a grid system (for easy navigation) or a more organic design (following rivers or hills), and what’s the best way to avoid common mistakes (like placing industrial zones next to residential areas)? Additionally, Cities: Skylines has hundreds of mods (like ‘Move It!’ for adjusting buildings or ‘Cities: Skylines Content Creator Pack’ for new assets)—What’s your favorite mod, and how did it improve your city-building experience (e.g., adding realistic traffic AI, new building styles)? Finally, the game has expansions like ‘Mass Transit’ and ‘Green Cities’—Which expansion was most useful, and did it make your city more realistic (e.g., adding trams or solar power) or more fun (e.g., adding amusement parks)? How does it compare to other city-builders (like SimCity 4)?
