One of the biggest problems is the core yield of coastal tiles: 1food 1 commerce.
This means with a fish, and fishing boats we get 3f 1g
A crab is even worse: they give only gold boost (was it 2g?), so WITH FISHING BOATS its 2f 3g or so.
Compare and contrast this to land resources:
Stone on grassland gives 2f 2p
Pasture is 3f 2p
On robot's vod, one of the tiles has 5 food without improvements:
Hills have even better yields, they have a base 3 yields (1f 2p for plains hills or 2f 1p for normal hills), so resources on hills are even better by 1yield. A forrested hill has 1 food 3 production unimproved.
Coastal cities already are disadvantaged. They get less housing, they have less land for districts and workable tiles. Sea is also less relevant since naval power doesn't allow them to take cities with a harbour district but build inland. Their only hope is to work resources in the sea.
How can a civ starting on coast compete with another civ that starts with unimproved tiles giving 5 food.
Also lighthouse now gives +1food +1 gold to the city, not per sea tile. So the situation remains dire.
I hope they do a balance pass on it. Is there something I'm missing guys?
