When you offer planet level, they will have the following benefits:

  • They will see all your planets. They'll receive the following information:
    • Temperature
    • Native population, race and government
    • Colonists
    • Supplies and cash
    • Mined (surface) minerals
    • Experience level
    • Presence of a starbase
  • They will be able to beam up cargo from your planets. In particular, they can:
  • Your starbases will help their ships. In detail:
    • their ships can clone at your planets, using up your minerals and your build points, and delaying your build.
    • their ships can use parts from your base's depot for super-refit
    • your bases will, with the appropriate Primary Order, load torpedoes onto their ships, refuel their ships, or unload them.
    • your bases can repair their ships
    • an ungiveable ship will normally explode when you force it to surrender with your base. If you offer planet level, the ship will be allowed to stay (and not surrender).
  • When their ships unload colonists to your planet, there will be no ground combat nor Imperial Assault. The clans will simply be added to the population.
  • When one of their ships tries to colonize on one of your planets, it will be permitted to land and disassemble; the goodies will be added to your planet. Normally, ships refuse to colonize on foreign planets.
