Separate construction prices, research costs and demo restrictions.
Two different costs
A building’s construction price and a research entry’s rank cost describe different purchases. Use the building page for the catalog construction figure and the linked research page for prerequisites and recorded rank costs.
Demo and full definitions
Some research expressions select different values in demo and full modes. This wiki displays the decoded branches separately. When more than one packaged definition uses the same research ID, their values are retained as alternatives. Presence in the archive does not prove availability.
Spend toward a goalInferred tip
Before buying a rank, identify the machine, tool or activity it improves. Following the prerequisite links can help you budget for a complete route to the capability you want. This is a planning suggestion, not a tested cheapest path.
