Does anyone have a reference to what the costs are to invading a planet are?
I can't find it in any of the instructions, or anywhere else, and wonder why the biggest deterence to invading other worlds in this game isn't the defenses of the enemy A.I., but it comes from the costs of 2,500 to 4,000 b.c. or more (money) per star system taken over.
Does it cost less if you raze the planet before you take it over, or more? etc.
