I made a (very) small mod to adjust "Vanguardism" in Victoria 3

Vanguard Fixed - Paradox Mods

Adjusts Vanguardism a little bit and makes Command Economy enactable with just Council Republic (without needing Autocracy / Oligarchy) to make the game experience less anti-communist.

Basically all it does is adjust the "Vanguardist" leader ideology (and Anarchism, base game has them liking professional army the most for some reason) and makes Command Economy enactable with just Council Republic (so without needing Autocracy / Oligarchy) to make the game experience a little bit less anti-communist.
