XC4 is the next mod that I am working on to incorporate into the mod, but it is proving difficult due to the lack of building slots that I currently have.

Here is the XC4 Colony System at Length with the factions from VE mod that would be assigned to them. Each colony has 4 levels, and then after that you have 'native culture' buildings that are in place at the beginning of the game, cannot be changed or built. These serve as identifiers for the culture of the region and have bonuses and/or penalties associated with them depending on which faction controls the region. They also are a base for the culture (western, eastern, tribal) that the region produces.

What I am listing is the Colony/Native building tree, followed by the unique native buildings associated with them.

My hope is that some of these can be combined, separated, or deleted to better make room to add into VE mod.

The main discussion will be at the discord server here: https://discord.gg/cmGWSPh but if it's a lengthy post that you don't want to get lost, leave it down below.

This is ten building trees and I only have room for 5. The easy/conventional way of adding it all in won't work this time, so I need to get creative. With that being said I am open minded, maybe there are some combinations that I don't see or ideas that I haven't thought of. Any help condensing these or doing away with them for something better is greatly appreciated!
