[Map] Ports should be buildable on river mouths
I don't have beta access yet. However, I noticed that ports cannot be built on every coastal tiles but beaches (from the trailer in the dev diary). Ancient ports usually were sheltered from winds - bays and river mouths, not beaches. My suggestions are:
- make ports buildable next to river mouths
- create a 'anchorage' feature for coastal tiles. Ports would be buildable there and next to rivers - not beaches
- a mid-game water/earth spell that would create an 'anchorage' on a random coastal tile.
These anchorages would also be assaultable - but with some additional attack penalties compared to beaches.
