Roads and ports!
It's an introduction to the planetary logistics system, and the next step toward making each planet feel like a living, breathing entity instead of just an economic data point.
With this foundation in place, more planet surface changes will follow soon.
Added planetary road networks for Space Age civilizations. Buildings now require a connection to a City Center to remain operational, civilizations autonomously expand roads to reconnect isolated infrastructure, and the Creator can Inspire or Demand road construction on specific surface tiles.
Added Sea Ports: Modern-era civilizations can establish coastal food ports, while Space Age Sea Ports extend City Center road networks across connected bodies of water and support overseas infrastructure.
