I created this mod for stellaris to address to the slower early game and abundent influence you get at late game.
Taken from the mod description on steam:
The aim with this mod is to push you quicker into the late game by allowing you to manage your influence as a way to boost your research. This mod provides two different systems, one for the early game and another for late game. Spaceport upgrades: Orbital Research Outpost Provides a flat bonus of 7 to each research stat. Additional Edicts: Drug enhanced research For a cost of 8 influence, provides a 200% boost to all research. Going to war For a cost of 5 influence, reduce fleet costs by 30%.
