The Production Queue
Parallel, per city, per type — not the queue you're picturing.
Capacity is 10 items per queue (both buildings and units). An 11th item is rejected outright.
CANCELLATION REFUNDS
| TYPE | MAX REFUND | DECAY SHAPE |
|---|---|---|
| BUILDINGS | 80% | Scales down toward completion — cancel instantly ≈ 80% back, cancel at 90% progress ≈ 8% back |
| UNITS | 75% | Same scaling shape as buildings |
| RESEARCH | 80% | Flat at 80% for roughly the first fifth of progress, then tapers to 0% by completion |
RUSHING
Rushing (instant-complete) costs remaining-time-percentage × original cost × 2. Rushing something already finished costs nothing; rushing something just started costs double the original price.
