🏛️ Wonder Events

15 events

The decision pop-ups that can fire the moment you complete a Wonder — dedicate the Ziggurat's terrace shrine, choose what the Lighthouse guides in, pick which family the Acropolis honors. Each card shows the wonder that triggers it and what every choice grants. Some roll a chance to appear (shown on the card); all are separate from the plain completion announcement, which always fires and grants +2/+4/+6/+8 Legitimacy by wonder tier. Building a wonder in its historical city (Pyramids in Memphis, Great Ziggurat in Ur, …) additionally pops a hidden Steam-achievement event with no in-game reward.

How yield rewards scale ↗ turn

A yield reward like +40 Science +10/city ↗turn is not a flat number. The amount you actually receive is:

(base + per-city × your cities) × turn multiplier

  • Per-city adds that much for every city you own (the rival's cities for Steal-Research-style effects).
  • Turn multiplier is ×1 up through turn 60, then ×(turn ÷ 60) after — ×1.5 at turn 90, ×2 at turn 120, ×3.3 at turn 200.

The number on each chip is the ×1 (base) value. Hover a yield chip for a cities × turn table of the real reward. Example — +40 Science +10/city with 4 cities: 80 early game → 120 at turn 90 → 160 at turn 120. The mission pages also have a live calculator. ("Tiny / Small / Average / Large" in the game are just preset base/per tiers — shown here as their real numbers.)

Weights are not in-game odds. Each story is gated by character/empire conditions (some hidden in-game), so its real frequency is filtered in ways the XML can't predict — community analytics differ a lot from raw weights. Treat the weight as the XML knob, not a probability.
