To give an clear overview of what is done and what will be done:
1.Create every country and assign it its provinces =Done
2.The same for cultures and religions = Done
3.Give every country the right army and navy = Not done
4.Give every country the right tech level = Nearly done
5.Give every country the right starting money and other things = Somewhat done
6.Remove many historical events that will be replaced with dynamic events = Much done
7.Create alliances and vassals that are present at the start of the game = I think completely done
8.Create centers of trade = Nearly done
9.Make some clean ups of the mod to remove stuff the mod doesn't change(reduces file size) = Somewhat done
10.Population for all the povinces = Not done
If i haven't forgotten anything these are the main prioritize to get the mod in an clean and working state.
After that comes the mod specific features or polishing things.
1.Create flags for the new nations and religions = Religions i did myself and they look ok. Countrys nothing done as of yet.
2.Make the start of the game more historical accurate = Not done
3.Finish clean up of the mod removing all unnecessary files = Not done(When i started the mod i just copied the vanilla folder in the mod folder and started changing things, so much of the files need now to be deleted because there just a copy of the vanilla files.)
4.Make dynamic event systems that allow for more possibilities = Only very few done
5.Making things like domestic policies effect your nation more( will be done through events ) = Not done
6.Some other things = Not done
7.Ai = Not done
Hope i didn't forgot anything.
So about an release date, point 1 was awful in doing, creating all the nations giving them provinces required to have so many things( id map and stuff ) open at the same time that the motivation i had was mostly gone when i finished setting up all the things i needed to start modding. That's why there where months where i have done nothing, but with this out of the way it's mostly just three things i need to have open: the game(maybe) the game folder and an editing programm. So to make things clear i have my motivation back now i will try to see how much im able to mod the next days and then i can decide on when it will be in 2016 or 2017 but even in an worst case scenario it shouldn't be 2018.
