I am still in the testing of how this impacts the game really, cause in the great scheme of things, pops are actually pretty much the only real driving force of economic power. So in order to be as powerfull as possible its always pop growth you want, each planet is just another pop growth multiplyer. Really did not understand why pdx left this out...in their empire size calculation.

HOLY MOTHER OF MOLY. The only feature that I solely missed from the upcoming Federation DLC. My play-styles have been simplified to getting as many pops as possible in my every playthrough which left me baffled at how well-thought out the game design was. Everyone needs to play with this mod.

My only worry is that AIs won't be able to handle this without its coded adjusted to take it into consideration in the upcoming DLC, but I guess if it's just 0.1(=3% research cost per 100 pops) it should be fine.
