Stellaris: 3.3.*
Not Achievement Friendly
This sub-mod adds no planets to the total number of planets in galaxy generation
This module adds 6 exotic planet types to your game, they are meant to play different than the regular oxygen-nitrogen races, with different ways of terraforming/creating new planets. They fall into two groups; toxic oxygen-nitrogen planets and exotic atmosphere planets. All planets have half Gaia bonuses, plus each has unique bonuses and a unique building.
Warning: These do not work with the Post Apocalyptic origin or any other origin that changes planet class. I am unable to limit those origins by planet
Toxic Oxygen-Nitrogen Planets
These planets have limited habitability on all other regular planets and a special way to terraform other worlds to their type. Regular races can colonize here but have no habitability bonuses.
Radiotropic World
Bonuses - Physics, Society, Food Unique SR: Rad Bloom Spores
This is a tomb/nuked planet that the lifeforms have adapted to the high levels of gamma radiation and now thrive. The blooms of these unique plants can be harvested and used to turn any planet into a Radiotropic World via terraforming, but only if you start on this world/have radiotrophic habitability.
Acid Worlds
Bonuses - Food, Minerals
This is a world of acid rain and sea, and the life that can survive here thrives. Currently, you can build a building that will make the planet more acidic, but I am planning on reworking this to work like Gaia Seeders, but only a paradise for Acid species. The acid wrecks havoc on robotic races until you have a tech to counteract the acid.
Exotic Atmospheres Planets
These planets are unique unto themselves; either too hot, too cold, too toxic or too pressurized for these species to live on other worlds, and regular races cannot live on their planets. Habitable versions of these worlds do not spawn randomly in the galaxy, just your homeworld and if you have guaranteed neighbours. But you can find terraforming candidates for each type that will allow you to build new ones, and once you have climate restoration you will be able to change regular worlds to these ones. Each has a special bonus and building.
Ammonia World
Bonuses - Food, Energy
"Rocky world with a nitrogen-ammonia atmosphere. This planet's variable gas is ammonia. With much higher atmospheric pressure than most terrestrial planets, the ammonia hydrosphere is stable.
Methane World
Bonuses - Food, Physics
Rocky world with a nitrogen-methane atmosphere and this planet's variable gas is methane. With temperatures, around -180 degrees Celsius, the methane hydrosphere is stable.
Sulfur World
Bonuses - Minerals, Society
This planet's variable gas is a mix of hydrogen sulfide and sulfur dioxide. High amounts of widely spread out volcanic activity cause the surface to be covered in thousands of sulfur hot springs.
Ash World
Bonuses - Energy, Minerals
Rocky world with a nitrogen-carbon dioxide-sulfur dioxide atmosphere. Although this young world has cooled from its molten past it still has considerable seismic and volcanic activity. The atmosphere on this planet is toxic to most creatures.
