Finish an Era with a Village of 1000 Prosperity and at least 8 Ocean Patches within borders
Our focus with this development is the Blue Whale. This food heavy creature is the ticket to generating a huge amount of underwater prosperity. As such the Ocean Giant needs 3 Swamp and 1 other Ambassador, while the Forest Giant needs 2 Desert, and 2 from Any.
After you’ve partaken in the usual Ambassador farming ritual set up the harbour town as you did for the Harbour Town Development. Two oceans leaving four tile in between. Now proceed to place the Whales…
Blue Whale, when placed alone, will generate in excess of 231 resources across five tiles. Place one of these on either side of the village and you’re already half way towards your goal and you’ve got plenty of ocean to play with - just leave the whale’s adjacent squares free.
Throw in Seabass, Marlin and Mackerel. Extend the Ocean by a tile or two if need be, but capitalize on the symbiosis; fish generate a stunning amount of stuff.
