Building placement
Day-night cycle
Each day and night cycle equals one simulated month.
Land value
Signature buildings and services change land value in their zone.
Milestone unlocks
Milestones grant development points and map tiles, from 9 starting tiles up to 441.
Modding API
Paradox Mods since 2024-03-25; mods can override game code.
Pause and speed control
Power grid
Generation, a connected grid, and batteries; solar output varies with weather and time of day and wind with wind strength.
Public transit lines
Random disasters
Floods, forest fires, and tornadoes, mitigated by disaster response services.
Seasons
Each map has a preset climate; winters bring snow.
Service coverage
Taxation
Tax rates, fees, and ordinances fund the city.
Tech tree
Development points are spent in a tree to unlock transport options and services.
Travel mode choice
Citizens compare driving, transit, and walking using a cost of time, comfort, money, and personal behavior, and parking fees enter the driving cost.
Weather
Weather and seasons affect solar and wind output and climate conditions.
core loop
zone and draw roads -> citizens choose homes, jobs, and routes by cost, time, and comfort -> taxes and fees fund services -> milestones grant development points and map tiles -> unlock transport and services -> expand
design notes
Route choice is a weighted cost over time, comfort, money, and behavior, so parking fees, transit fares, and lane choice shift where agents go, and the first game's cap of about 65,000 rendered citizens is replaced by a hardware limit. One in-game day and night stands for a month, so daily traffic rhythms and seasonal climate run on different scales. The launch drew criticism for performance and its economy simulation, console versions were delayed indefinitely in 2024, and development moved from Colossal Order to Iceflake Studios after a November 2025 announcement.
