Cities: Skylines is Colossal Order's city-building simulation that became the definitive modern city builder after SimCity 2013's failure. You build and manage a city from a small town to a metropolis of hundreds of thousands, handling traffic, zoning, utilities, public transport, and citizen happiness. The game's deep traffic simulation is both its greatest strength and biggest challenge — everything flows through your road network. With extensive mod support through the Steam Workshop, the game's potential is nearly limitless.
Picking the right build determines how your experience plays out. These builds are ranked by overall effectiveness — factoring in damage, survivability, gear requirements, and how well they scale into endgame.
Quick Rankings
| Build | Tier | Playstyle | Core Gear |
|---|---|---|---|
| Road Network | S | Plan road networks before zoning. Build capacity ahead of demand. | Road type hierarchy, roundabouts, one-way systems |
| Transit Hub | S | Build metro lines along major corridors, feed with buses, connect to trains. | Metro stations, Bus Depots, Multi-modal hubs, Monorail |
| Industrial Zone | A | Place industry with direct highway access, connect cargo rail, keep away from residential. | Cargo terminals, highway access, buffer zones |
| Commercial Core | A | Zone commercial near transit hubs and residential density. | Transit access, pedestrian paths, tourism buildings |
| Residential Suburb | A | Create quiet neighborhoods with dead-end roads and ample green space. | Cul-de-sacs, parks, schools, tree-lined roads |
S-Tier: Road Network
The foundation of every successful city. Use highway → arterial → collector → local road hierarchy. Roundabouts for intersections, highway off-ramps for district access. One-way roads double capacity. Grid layouts work but stagger intersections to prevent gridlock.
Core Setup
| Slot | Choice | Why |
|---|---|---|
| Primary Equipment | Roundabouts | The single most effective traffic tool. |
| Core Gear | Road type hierarchy, roundabouts, one-way systems | Maximizes build potential |
| Stat Priority | Traffic flow > Capacity > Aesthetics | Optimal scaling |
| Key Mechanic | traffic management | Traffic is the core challenge. |
How to Play Road Network
Plan road networks before zoning. Build capacity ahead of demand.
The foundation of every successful city. Use highway → arterial → collector → local road hierarchy. Roundabouts for intersections, highway off-ramps for district access. One-way roads double capacity. Grid layouts work but stagger intersections to prevent gridlock.
What makes this build work: The synergy between Roundabouts and traffic management creates a gameplay loop that outperforms other options. Core gear like Road type hierarchy, roundabouts, one-way systems amplifies this further.
Pros:
- Highest overall performance
- Clear stat priority (Traffic flow > Capacity > Aesthetics) makes gearing straightforward
- Works in all content types
Cons:
- Popular pick, resources may be contested
- Needs specific gear to reach full potential
S-Tier: Transit Hub
Public transport networks that move citizens without cars. Metro lines connecting residential to commercial/office areas. Bus feeder routes to metro stations. Train for intercity connections. Multi-modal hubs (bus + metro + train) maximize efficiency.
Core Setup
| Slot | Choice | Why |
|---|---|---|
| Primary Equipment | Highway Interchanges | Grade-separated interchanges (cloverleaf, turbine, stack) prevent highway traffic from stopping. |
| Core Gear | Metro stations, Bus Depots, Multi-modal hubs, Monorail | Maximizes build potential |
| Stat Priority | Metro coverage > Bus feeders > Train connections | Optimal scaling |
| Key Mechanic | district zoning | Residential (green), Commercial (blue), Industrial (yellow), and Office (teal) zones are painted along roads. |

- Works in all content types
Cons:
- Lower peak damage than S-tier
- Needs specific gear to reach full potential
A-Tier: Industrial Zone
Industrial zones should be separated from residential via highways or buffer zones. Industry generates truck traffic, noise, and pollution. Cargo train terminals and harbor connections reduce truck traffic. Generic industry upgrades to offices as education increases.
Core Setup
| Slot | Choice | Why |
|---|---|---|
| Primary Equipment | Bike Lanes | Bike lanes on roads encourage cycling, reducing car traffic. |
| Core Gear | Cargo terminals, highway access, buffer zones | Maximizes build potential |
| Stat Priority | Highway access > Cargo rail/harbor > Pollution isolation | Optimal scaling |
| Key Mechanic | public transport | Buses, metro, trams, trains, ferries, monorails, and cable cars move citizens without cars. |
How to Play Industrial Zone

Build Progression Path
- Start with Transit Hub — the most forgiving option for learning the game
- Transition to Road Network once you understand core mechanics and have access to Roundabouts
- Keep a Industrial Zone setup for content that keeps killing you
- Try Residential Suburb for a fresh experience once you've mastered the basics
Gearing Tips
- Invest in your primary equipment first — it gives the biggest power spike
- Roundabouts fix 90% of traffic problems. Any intersection below 80% traffic flow should be converted to a roundabout.
- Don't zone too much at once — grow gradually. Zoning 10,000 residential units simultaneously creates a death wave 60 in-game years later when they all die at once.
- Don't spread upgrade resources across multiple builds until endgame
