I have some simple questions on invading extreme colonies.
1.When you invade an extreme colony, like Barren or Radioactive, are you require to research that specific technology to colonize it first before an invasion force can even land on this world, much less maintain it if you win the invasion?
2. If you do not have to research this specific technology first to invade an extreme world, would not your troops be at a disadvantage, like the effects of heavy gravity or unable to breath? If by some miracle you win this world, later on would you be able to colonize other worlds like it as the game goes on?
