This mod is 100% stand-alone and will work without Planetary Diversity.

More Demos and more details in the descriptions are coming; I have just been busy with work and will update the rest as soon as possible! Thanks for your patience.




Capital arcs have been replaced with a decision that can be done on any Arcology/Hive/Machine World that you can build. This will change the planet portrait, and in the case of the Vanilla City World, it will also change the planet model. They all take up three districts but give you 18 jobs and local and empire-wide bonuses. There is also a Ringworlds (full Ringworlds only) and Habitat version once you have unlocked the anti-gravity building tech.


These arcologies are made via decisions. Once a planet meets the requirements, you may select its respective decision, just as regular arcologies work. Each arc gets a particular modifier that grants certain jobs per 10 pops and planet-wide percentage buffs that reflect the specific arcology you have selected. You must have taken one of two traditions; keep reading for more info.

A utopian version of an ecumenopolis with large country-sized nature parks. Unlocked by taking the Adaptability or Discovery tradition tree. It includes standard residential, leisure, and administrative districts, a standard Factory district (+10 housing, +6 artisan jobs), and its specialized Research district (+10 housing, +6 researcher jobs). Its modifier provides +1 Ranger job per 10 pops and +10% happiness at the cost of -3 maximum districts.

This is a trade and industry-focused arc. Unlocked by the Prosperity or Mercantile Tradition Tree. It includes standard residential, leisure, and administrative districts and its specialized Industrial (+10 housing, +3 artisan jobs, +3 metallurgist jobs) and Commercial (+10 housing, +6 Trader jobs) districts. Its modifier provides +1 Clerk job per 10 pops and +10% Trade value from Living Standards at the cost of -3 maximum districts.

This is a Military Powerhouse that is more focused on the admin and background of your military rather than defense. Unlocked by the Supremacy or Unyielding tradition tree. It includes standard residential, leisure, and administrative districts, as well as standard Foundry districts (+10 housing, +6 Metallurgist jobs) and its specialized Logistical districts (+10 housing, +6 Logistics specialist jobs).
