I've created a fish race, but it's proving difficult to play as them. The swimmable token allows them to exist in the ocean, but not their structures. I can settle in large pools in a swamp, but the admin center itself has to be on land. My goal is to have their settlements be in the ocean. If I can use it in the boat update I can prey on travellers.
But really I was just wondering: is there a better way to make ocean structures than giving them the swimmable construction req. ?
