Mod "Guilli's Planet Modifiers" for Stellaris.
What does this mod do?
Wondrous Planets
At the start of the game, up to one planet of each planet type will be chosen as a wondrous planet. This planet will have unique planetary features on it that provide very large bonuses! Once you have surveyed and discovered a planet like this (or the AI has), the planet name will change to a different colour.
Discovery! Events
When your science ships survey a planet and discover a special modifier on that planet an event will pop up telling you about it. This only happens the first time you discover this modifier. You will have the option to spend some influence to tell your scientist to take another look for extra rewards...
Colony Events
Over 40 mini colony events have been added that can trigger after you have colonised a world with this mod'€™s modifiers. Several capital event chains to do with your ethic choices have also been added.
Valuable World Modifier
Some dead worlds (barren, frozen, etc) that have specific modifiers will also have a 'valuable world' modifier. This modifier allows terraforming of this world with the right technologies.
Terraforming Interaction
When you terraform a planet the following will happen:
Crisis Interaction
Crisis that purge or change planets will have improved interactions with planet modifiers. They will remove and/or roll new modifiers as well.
