I was recently calculating whats a better investment for food trickle, a ice house or a farmstead and cows garrisoned.   ICE HOUSE (Limit: 5) Base building: Cost: 100 stone, 100 wood Build time: 60 s Trickle: 1 food / 2 s (0.5 food/s) Aqueduct upgrade: Cost: 300 stone, 300 wood Research: 40 s Trickle: 2 food / 2 s (1.0 food/s) 5 ICE HOUSES (max): 5 × (100 stone + 100 wood) = 500 stone, 500 wood 1 × (300 stone + 300 wood) = 300 stone, 300 woo
