Terraforming Decay
Adds a few modifiers and a couple of decisions, based around the idea that terraforming isn’t forever, and that these artificial biospheres will break down if not maintained. Uninhabited, terraformed worlds will have a modifier applied and decay over a long period of time, going from Gaia down to the Wet worlds, then either Cold or Dry and finally uninhabitable. Ecumenopolis’ will decay into Relic worlds if left uninhabited long enough.
Colonised worlds and Consecrated worlds are protected, and this mod includes a further decision to protect a planets biosphere, locked behind the prerequisites Terrestrial Sculpting and Shields. This takes the form of two decisions, one to ‘activate’ and one to ‘deactivate’ the field on uncolonised, terraformed worlds. It costs Influence and Energy both to activate and deactivate, though with a higher cost to activate, and will apply a modifier to prevent it being applied a decay modifier. The planet will also suffer from -20% Pop Growth and -20% Habitability whilst the field is active (to simulate the effects it has on the higher brain functions of sentients.
1 of 4 new Modifiers applied to decaying terraformed worlds (plus Terraforming Candidate.)
- Dusty Hallways = 100 year timer – Decays Ecumenopolis’ to Relic
- Paradise Lost = 25 year timer – Decay Gaia into one of the Wet worlds
- Terraforming Breakdown = 50 year timer – Decay Wet worlds into Dry or Cold
- Biosphere Dying = 150 year timer – Decay Dry or Cold world into Barren or Frozen
- Terraforming Candidate = Applied to Barren/Frozen worlds upon decay
2 decisions to control ‘stabilisation field’ and a modifier to protect the planet from decay
- Stabilise Planet – 150 Inf, 2k Energy – Adds Biosphere Stable modifier
- Cease Stabilisation – 50 Inf, 500 Energy – Removes Biosphere Stable modifier
- Biosphere Stable – Modifier to protect planet from receiving decay. -20% pop growth/habitability.
Consecrated worlds, worlds currently undergoing terraforming and worlds with an active Stabilisation Field are exempt from decay modifiers, as are any world outside the main worlds outlined here. Only worlds which have been terraformed will have a modifier applied.
Ecumenopolis’ will decay to Relic worlds whether or not the planet has ever been terraformed.
This only adds a few new files and uses gfx already in game, so it should be fine with anything that doesn’t replace the vanilla planets completely.
If you feel like abandoning more than just terraformed planets, try my mod Abandon Sector, which destroys all Starbases, Mining and Science stations within a sectors borders: https://steamcommunity.com/sharedfiles/filedetails/?id=2582344179
Though I say planned, I don’t know if/when I have the time so these are just suggested features I might put in I guess.
- Permanent stabilisation – technology prerequisite, allows you to terraform as normal with no decay as your Empire has ‘perfected’ terraforming.
- Have a shield graphic on constantly
- Make my own shield graphic/icons
- Field decay if no system owner?
- Extra long timer on Relic worlds to decay into a normal world (with appropriate blockers).
- Localisation
