Reason: Update mod to version: 10.04.21
HOI4 ULTRA's goal is to give a historical feeling to Heart of Iron. Our ambition is to make the less changes as possible from the vanilla, but rather adapt it to a real historical balance and is meant to be played in Multiplayer.
The original goal was to give an historical repartition of the industry, but we decided to add/fix/tweak other contents we feel important.
Reasons to play or not to play ULTRA
Main feature - Industrial rebalance
The primary objective of our work was to "correct" the industrial balance in the game :
In vanilla, industry is balanced around "playability" and not around History. For the HOI4 devs team, each minor country should be "playable", the Axis should have a chance to "win", global conquest should be a possible achievment...
We don't agree with this view and want rather to play in a situation with historical settings concerning the relative power of each countries.
That's why we did a research work about the industry in the WWII timelapse in order to translate it into a mod. Our main sources are The Wages of Destruction from Adam Tooze and The Rise and Fall of the Great Powers by Paul Kennedy.
From the later, we took the concept of "war potential" for each 1936 country and translate it into ingame industry (civilian, military and dockyard). To gives some figures, the 7 Great powers have more than 90% of the world IC and the gap between the last major power (Italy) and the first (the USA) is more than 1 to 10.
To have a better repartition, we made each vanilla IC equivalent to 2 IC in the mod.
To stay in the border of plausible, we also had to change 2 keys elements : the industrial growth rate (nerfing heavily industrial snowballing, we now get a growth rate under 10% per year in 1936) and the ressources system. Coal, Iron and Bauxite were added and globaly ressources are less expensive to get (depending of the ressource) to avoid overpowered minors from lots of ressources and majors having to trade away half of their industry.
