Evaluation
How Tiers Are Decided
A building can have impressive raw numbers and still rank lower if it arrives too late, blocks a better slot, or fails against current pressure strategies.
ROI per Slot
Every building competes for finite land. We weigh production rate, unlock cost, and ramp time.
Meta Fit
Does the building enable the current top archetypes: Economy First, Air Rush, or Territory Control?
Late-Game Relevance
Buildings that fall off after Stage 3 cannot earn S, no matter how strong their early curve is.
