Treasure Fleets should need reach a port to unload their cargo; trade winds?

I believe the maps in Old World have something like that, with Lush terrain being on one specific side of Mountains, representing rain patterns?

I believe the maps in Old World have something like that, with Lush terrain being on one specific side of Mountains, representing rain patterns?

- And there was a map generation-type Mod in Civ V, the name of which escapes me after all these years, which did something of the same thing: modeled 'rain shadow' and primary wind direction for its effect on terrain and biome. As I remember, the results tended to be a bit too extreme for good play: maps became very predictable on where jungles, rain forests, deserts would form on every continent, without variation.

But I suppose it was a start.
