Systems controlled by interstellar civilizations are separated into four groups, core systems, inner systems, outer systems, and claimed systems. These are classified based on a ranking system for the development and capabilities of each system, with each system ranked out of 10 for 5 separate categories:
Population: the number of people in the system
Agriculture: the food production of each system
Industry: the number, and effectiveness of factories and shipyards in the system.
Infrastructure: the existence and effectiveness of infrastructure in the system (ports, ground to orbit mass drivers, trains, roads, ect)
resource extraction: the amount of the materials extracted from the system
The combined rankings of all categories determines what the system is designated as:
Core System: a score of over 35
Inner system: a score of over 25
Outer system: a score of over 10
Claimed system: a score of under 10

Colonization philosophy: among humanity, there are two primary colonization models practiced for colonizing new systems, the sol model, and the Centauri model. The sol model has a significantly more spread out population, with villages, towns, and cities all existing and specializing the primary component of their economies off of one or a few specific industries, and then trading with each other to create a economic ecosystem. The main problem with this model is the extreme requirements for infrastructure so that the economy can smoothly transfer people and goods between the settlements and the extreme difficulty to defend such a colony with everything, so spread out. The Centauri model focuses on centralizing all of the colonial population in a few hive cities which are near self-sufficient but also trading with each other. The main problem with the Centauri model is heat dissipation, dissipating, the heat of all of those industries, and all of those people out of the hive means that the city has to A. Be located in an area where it will be easier to radiate heat (on low temperature worlds, dense atmosphere worlds, near sources of water, etc) limiting the possible locations for the city, Or B. Devote the majority of their surface area to heat dissipation, causing it to be unavailable for other uses.
