From Sins of a Solar Empire
- There are six different planetary improvements that an empire can use to upgrade its colonies.
[edit] Civilian Infrastructure
This upgrade increases the maximum population a colony can sustain. It also eliminates the planet underdevelopment penalty associated with new colonies. This upgrade is important because the larger the population of a planet, the greater the tax income it contributes to an empire. Terran planets usually support the largest infrastructure and Asteroids the least (dead asteroids, even more so), but it's still advisable to max this out quickly, as it will lead to increased credit production and prevent you from losing income to under-development.
[edit] Emergency Facilities
This upgrade increases the planet's health by allowing the populace of the planet to "build" various shelters and emergency services to protect them from a multitude of disasters. Thus allowing it to survive extended planetary bombardment. This upgrade is important because it gives defending fleets more time to arrive and to destroy the attacking fleet before a colony is destroyed.
[edit] Explore Planet
This upgrade explores the planet for any special
Planet Bonuses or
Artifacts a planet may possess. This upgrade is important because the special bonuses can make the planet more efficient and artifacts provide empire wide bonuses.
[edit] Designate Capital Planet
This upgrade makes the planet the new capital of an empire. This upgrade can be useful if an empire's current capital is in a bad location, since allegiance is based upon a planet's position in relation to the capital.
[edit] Logistics Capacity
This upgrade increases the number of logistic slots available on a planet. Logistics slots are used for constructing productive
Orbital Structures such as Shipyards, Refineries, and Trade Ports. This upgrade can be useful if an empires wants to build additional research or productive structures. Upgrading Logistical Capacity will also produce more constructor vessels, which enables faster assembly when you are building a number of structures.
[edit] Tactical Capacity
This upgrade increases the number of tactical slots available on a planet. Tactical slots are used for constructing defensive
Orbital Structures such as Cannons, Hangar Bays, and Repair Platforms. This upgrade can be useful if an empire wants to permanently augment a colony's defense. Upgrading Tactical Capacity will also produce more constructor vessels, which enables faster assembly when you are building a number of structures.
