This mod changes the yields of terrains and features. I didn't like the additive nature of yields in the base game and wanted to differentiate terrain types more. Changes are as follows
Citizens eat 3 food per turn (up from 2)
Grassland yields 3 food
Plains yields 1 food, 2 production
Tundra yields 2 food
Desert yields 1 food, 1 production
FloodPlains yield 4 food, but cannot have farms
Hills -1 food, +1 production
Marsh -1 food, +1 culture
Rainforest +2 food, -2 production
Woods no effect
The most food benefit you can gain from a resource is +1
Also changed Torres Del Paine to only spawn in tundra (too powerful otherwise), increased food on any food related natural wonder (Great Barrier Reef, Cliffs of Dover, Dead Sea, Crater Lake, Pantanal).
Petra does not yield extra production and Huey yields an extra food (Bring in line to be similar to pre mod effects).
