Makes all the infinite technologies only researchable a finite number of times (defaults to once), thus allowing you to unlock every technology.
Small changes concerning balance, gameplay, or graphics.
Would be cool to see an option to limit the researches to a number (in the settings) instead of just making them a single research. I would love to make them cap at like 25 or something so they go on for a while, but are not infinite.
I already have such options, did you look in Settings -> Mod Settings?
