With this you can limit planets to certain biomes. I have only done it to two biomes atm but I will add more as time progresses. YOU DONT NEED A NEW SAVE! JUST TESTED IT!!!!!!!!!!!!!!! You can limit the planets to a green planets with lush green grass, or the hexagon(weird) biome with all colors. Both of these remove the chance of abandoned planets.
Just a Small Mod that changes the Distance of the Planets.
What shoudl i say more. I just want to say that the extreme Version is only for Crazy people. You will really sense the changes.
That Mod Edit Solargenerationglobal.mbin. Every other Mod that edits the same is incompatible.
