Building upgrades
Upgradable buildings are part of the announced Early Access scope. Exact effects, material requirements and payback values await current-build evidence.
Compare the same output
For an upgrade decision, compare the same resource and time period before and after the change. Additional worker requirements or inputs can offset a larger output number.
Use payback carefully
The manual ROI worksheet divides an entered cost by entered additional net income. It works only if both use the same currency and period. It does not invent a price for construction materials or promise an optimal upgrade.
Preserve the old measurement
Record the previous build and conditions alongside the new result. If a patch changes the recipe, revise the inputs before reusing a saved worksheet.
