-### Rules for selecting existing planet mods
-
-#### Heavy adjustments
-
-Finished planets that are almost what we need for Space Age Extended probably don't exist. It's clear that existing modded planets needs to be included but heavily adjusted to our needs. The original mod authors must agree to this and be informed and given the chance to include at least some of the adjustments themselves or make them settings of their mod.
-
-#### No cargo drop restrictions
-
-Wube didn't do it and we should stick to it too. The player can always choose to not import things from other planets when starting on a new one but that's not for the mod authors to decide.
-
-There should be at most one exception if a planet fits really well but falls apart without this restriction.
-
-Planets that natively restrict cargo drops shall make that configurable and Space Age Extended enforces it to be off.
-
-#### No puzzles
-
-Puzzle planets don't fit the Wube style and should be avoided. That probably rules out planets like Cerys, Rubia and Cubium.
-
-#### Add new settings
-
-Sometimes it's way easier to not do something in the first place instead of undoing it afterwards. The mod author must be willing to add new settings for such cases.
-
-#### Split the mod
-
-If there are mandatory dependencies that we don't want to include, the mod author must be willing to split the mod into a "base" mod without those dependencies (marked as internal) and a "standalone" mod that adds those things.

 * Most progressive recipes should be disabled by default. The impact is just too big to be mainstream.
