From the "What We Know" thread:
I think it's an pretty good tree, I like some benefits a lot and dislike others. With a few changes, it can be awesome.
Here are my ideas:
-Opener: +1 movement and sight for all naval units. This is good as is.
-Maritime Culture (changed Maritime Infrastructure) +3 production in coastal cities, +5 XP for naval units, Naval units fighting at least 2 tiles away from the nearest coastal tile get +10% strength (applies to melee and ranged)
What I did here is added some bonuses to the actual power of naval units, and renamed to en
compass (see what I did there?) all of these bonuses
-Surveying: (replaced Merchant Navy) Land units ignore terrain cost and have the survivalism promotion when they are on landmasses you do not have a city on.
Here you get a benefit to land exploration.
-Treasure Fleet: +4 gold from all of your sea trade routes. Fine as is.
-Colonial Riches (replaced naval tradition) Each new
type of luxury you acquire on new landmasses not found on the continent with your capital gives +2 happiness, and +3 gold.
This is situational depending on how many types of luxuries are found on your starting landmass, and it encourages you to make cities on other continents and to have resource diversity in these cities.
-Advanced Colonialism (replaced Navigation school) All cities founded on landmasses that do not contain your capital start with a free monument, walls, and granary. They also get a +15% bonus (stacks) to the production of buildings. However, these cities produce 7
unhappiness when founded. This effect decreases by 1
unhappiness every 10 turns until it rests at 3.
This policy also encourages colonizing, but gives a penalty to prevent being too OP.
-Finisher: Shows hidden antiquity sites, can purchase great admirals with faith in the industrial era.
Good as is.
So, the tree has:
3 Maritime Policies
2 colonialism Policies
2 land exploration Policies (surveying and the finisher)
My ideas would make exploration really unique and diverse, so anyone wanting to expand across oceans or looking for naval power would definitely pick it. It might even be a little OP, maybe.
Give me your feedback!
