Balanced Research Buildings Reduce Corruption

This mod adds a stacking, modest corruption reduction effect to each level of each culture's research/lore buildings. UPDATE 2020: After a two year delay this mod finally supports the Rise of the Republic campaign! Big thanks to AkaalElite for updating and testing the mod for this DLC! Please check out his mod QOL Improvements which does what this mod does, and more!

Level 2 -1% of current corruption
Level 3 -2% of current corruption
Level 4 -3% of current corruption
Level 5 -5% of current corruption (Restricted to certain factions)

This mod can be added and removed from saves at will, so feel free to experiment or use it temporarily to get you through a rough patch.

I dislike the ridiculous levels to which corruption soars in the base game but felt like all of the mods I could find that addressed the issue were too powerful for my tastes. So I have made this balanced version. Now as you build and upgrade more research buildings, something you should be doing anyway to maximise your research speed, you will add a stacking reduction to your factions current corruption value. See the attached screenshot for an example of late game corruption and income with normal play.

For example of how this mod works exactly, if you have seven Akademia (the level 4 Greek research building) than your current corruption value would be reduced by 21%. So if you had 50% corruption and no other sources of corruption reduction your corruption would be reduced to 39.5%. However this will stack with reductions from research. I like to end up with at least fifteen research buildings over the course of my campaign, often more, and working together with the research options from the philosophy tree you can end up with a very low corruption value. 0% even if you went crazy and built like thirty level 4 research buildings!

An added bonus to this mod is that it both encourages you to keep on top of your research buildings, helping out your technology overall, and reduces the necessity to rush down the philosophy tree.

Please note this mod only applies corruption reduction to dedicated research buildings typically found in province capitals. Minor settlement (glass) for instance will not lower your corruption. However if you do find a dedicated province capital research building that this mod does not work for please let me know. I mainly play Grand Campaign and cannot test every faction or DLC.

This mod was inspired by Research Buildings Reduce Corruption and the other such mods that preceded it. However my mod was built from the ground up and does not include any of the effects of the previous mods other than reducing corruption values. However I am very grateful to the mod authors before me that inspired me to create this mod. :)
