There are three major points that would determine if a map can be accepted into Territory Conquest.

  1. Location
    1. How strategic the location's terrain and geography would be in-game.
    2. How well known the region is in general.
    3. Similarity to current maps.
  2. Design
    1. Territory design consistency in regions.
    2. Avoid too small / large / long territories.
    3. Avoid too many territories in a state.
  3. Balance (relative to spawns)
    1. Cities.
    2. Territory sizes.
    3. Geographic obstacles.
