This thread is built on necroposts so I'll join in with a question.
Does changing the sea level also influence how shallow/deep water is generated? As in higher sea levels means less shallow water between landmasses. Sometimes even continents far apart can have small shallow trails snaking between them.
I've always been curious about that. I ask because If I was playing a map like archipelago I would rather have deeper oceans because it would mean my enemies would have to get more techs before they could get to me. Plus it can be more interesting to not meet all of the other civs within the first era.
