Unique Decisions Balance Thread

[Funak]

Figured I'd start a thread on this since Gazebo asked for a list on things that weren't working properly. I mostly copied this straight out of the E&D wikia and edited it to fit better, removing lore and such that isn't necessary for the discussion.

All of these unique decisions are balanced around the base-game, which means some of them are bound to be completely out of control in CPP, and because people like this mod, the benevolent Gazebo have promised that he might take a look at it assuming we can list things out properly. I guess anyone else with the know-how could do this for him, but since I'm incompetent and not willing to learn, I'll just do what I can, which is editing this huge pile of text into a readable format.

[Opera]

I won't do them all for now, just a few.

America

Emancipation Proclamation could perhaps get another prereq; it seems very strong for very little investment. It's not a problem per se, just something to keep in mind... A lot of decisions hand free buffs.

I wonder how the Louisiana Purchase interacts with Pioneers. A flavorful change could give cities settled along rivers all the territory adjacent to rivers, representing the Mississippi.

Byzantium

Succession Laws is really bad... 400 gold for 2 magistrates? I'm not convinced this is worth anything.

The Theodosian Wall makes me think Byzantium should get faith from all defensive buildings (walls, castle, etc.) as part of her UA, as well as perhaps 1 or 2 faith from her palace. Byzantium nearly never found a religion in my game (might be a flavor issue?) because by the time she gets to Theology (for the free prophet), all available religions are founded or close to it.

 

[Funak]

One thing that comes to mind is:

Sweden

I don't know if it has already been changed, and checking it out takes ages since it involves starting a new game as Sweden. But since Caroleans were moved to gunpowder, this decision should probably also be moved there.
