I don't understand. Why narrow the scope of this dlc so much, to only 5 republic? What prevents inland republic from working exactly with these mechanics? I mean the sea trade isn't exactly the only trade existing, and republic aren't necessarily all about trade.
Right now it seems more like Crusader Kings II: The Republic-but-wait-only-five-of-them-and-only-those-bordering-a-seacost. Also you can invest in golden toilet seats for your super palace which totally makes you more powerful!
I mean come on I love you paradox but this seems a bit disappointing here.
This, I mean sure it might be a bit boring without the tradepost mechanics, but so is playing a feudal ruler in Iceland, just let the player decide if it is boring or not. The succession and politics sound fun enough even without the maritime mechanics
