TCS Improved Water Yields

This mod overhauls how the Harbor and its buildings work.

The design philosophy behind this mod is threefold:

• To make coastal cities or cities with many sea tiles more balanced.
  
• To reward careful district planning.
  
• To reward investment over time.

To that end, base terrain yields are unchanged. Rather, building the Harbor district immediately increases all sea terrain yields by 1 food. Further investment into the district is rewarded in more valuable resources and an additional terrain bonus.

Ultimately, bare coast tiles will yield 3f/2g and bare ocean tiles will yield 3f/1g. Resources, on the other hand, will be very fertile. Bare sea tiles in this mod are not designed to be incredibly productive, but are balanced so that working them will still be a net gain. Well-placed harbors can provide extraordinarily large amounts of food, and well-balanced specialists can add just a bit of extra production to island cities.

+2 food and +1 gold for adjacent City Center. +1 food and +1 gold per adjacent sea resource

Lighthouse: +1 food to all sea resources
Shipyard: production equal to Harbor Gold adjacency bonus, +1 gold to coast and ocean tiles
Seaport: +1 food to coast and ocean tiles, +1 production to all sea resources

These changes replace all prior building yields.

Harbor Specialists: provide +1 food, +1 gold, and +1 production

Naval Infrastructure and Economic Union policies increase both the Harbor food and gold adjacency bonuses by 100%

Cartography now increases Fishing Boat gold by +1 instead of +2

Compatible with the Summer 2017 Update

Fish Farms is compatible with this mod. Several changes are made to Fish Farms if both mods are activated:

• Fishing Boats no longer gain adjacency bonuses
  
• The additional Harbor gold adjacency bonus is removed
  
• The additional trade route gold bonus from Harbors is reduced from 2 to 1
