Rivers - big and small

[Winged Hussar]

When creating realistic and detailed earth maps, at certain scales there's just too many rivers making movement difficult.

Just an idea:

Big river - unchanged from the current rivers we have

Small river - visually, a skinnier version of the current river, same source of fresh water and defensive/offensive penalties, but no movement penalty. These would be perfect for tributaries, making more aesthetic maps, and making movement more vanilla.

And huge river, like the Nile in Gifts of the Nile, that naval units can travel up.
