Factories gain efficiency the longer they produce the same equipment. Retooling to a new tank model causes a temporary "efficiency cap" drop. The early game (1936–1938) is a race for
Always keep your Industrial and Electronic Engineering techs up to date, as they provide multiplicative bonuses to everything else.
Victory in HoI4 is often decided in the factories years before the first shot is fired.
Writing a "long paper" or guide on requires breaking down its massive mechanical complexity into digestible pillars. Whether you are preparing a master's thesis on the game's systems or a comprehensive strategy guide for a community, the structure below covers the essential "heats" or core mechanics that drive the game. 🏛️ Pillar I: Political Foundation & Economy
