A building payback window, settlement development choice and Economic Victory gap with local scenario persistence.
Compare two buildings by their added resource and production commitment. Open the other tabs for a separate payback assessment, settlement development or Economic Victory gap.
Take the cost and completion time of two buildings from your game. Compare their gain in one resource. Gold, Science and Culture keep their own units; no conversion to production is needed.
Translate expected per-turn benefit into a production equivalent. This is your value assessment, not a hidden game formula.
Compare current per-turn value with expected value after development. The model prices only the increment and assigns no universal value to a city.
Enter values from the game interface. The model adds planned sources without turning them into an invented per-turn rate.
Official material confirms the structure of the current version. Every numeric value comes from the game interface and stays on the device.
