Firaxis, please end the ocean tile and seaside city discrimination. My suggestions: Allow workers to build work boats in a city rather than having the city build them. That should help coastal cities get started without having to divert so much production or gold into work boats. Food and gold yields of ocean tiles needs to increase in some manner as the game progresses. A riverside city will get access to several 4 food 1 gold farms as soon as Civil Service is researched, whereas a seaside city will be stuck with 2 food 1 gold ocean tiles. One way to remedy this could as follows: with the Compass tech coastal tiles give 1 extra food and with Navigation tech coastal tiles give 1 extra gold. The Colossus should probably limited to giving 1 extra gold on coastal tiles only (if it isn't reworked entirely to boost trade route income). To further increase the incentive of seaside cities, add more ocean luxuy resources and possibly increase the number of bonus resources in deep ocean tiles. Another seaside city oriented pantheon belief would also be nice. Generally a seaside city is more open to attacks compared to an inland city, as well as having lower production. In return seaside cities should at least have similar food income and better gold income.
