Build a city from a single road segment on an empty plot and watch it grow into a living, breathing metropolis. Zone residential, commercial and industrial districts. Lay roads, rail and transit. Manage the flow of water, electricity, garbage and education. Balance the city's budget against the demands of a population that is always growing, always changing and always wanting more.

Cities: Skylines II expands the landmark 2015 city builder with an entirely new simulation engine. The economy model now tracks individual citizens from birth to death — their employment, education, shopping habits and commutes all feed back into the city's economic performance. Building sizes scale with demand. Roads can curve and intersect freely without grid constraints. Climate and weather affect traffic and infrastructure needs across seasons. The maps are five times larger than the original. Paradox has released multiple expansion packs — Waterfronts, Bridges and Ports, and themed Season Passes — adding maritime infrastructure, waterfront zoning and cosmetic building sets. The mod toolkit was overhauled after launch to improve creator accessibility.

Key Features: • Full citizen lifecycle simulation — every resident tracked from birth through employment to death • Free-form road building • Mixed-use zoning • Seasonal weather affecting infrastructure • Maps 5× larger than Cities: Skylines - deep budget and policy management • Waterfronts + Bridges & Ports expansions
