How is a sucessful/unsucessful colony invasion decided?

from Stardock Forums
Just wondering how GalCiv decides who wins - Attacker or Defender.

Just finished a game where I could not seem to invade a colony. In the end the colony that started with a population of 8K cost me 13.5K to invade and win. :sniff!: On the invasion screen these were the numbers for each transport[4 in total]:
Attackers: Defenders:
Offence: 9 5
Defence: 9 6
Tech: 14 (I think) 1.0
The chance rollers were in the region of ~60 vs ~6
My invasion was 5K, 5K, 2.5K, 1K a turn apart as I rerouted 3 transports to this colony.

1 other colony of this race was also just as difficult, but 4 others, several bigger, were easy to knock off, thus leaving a number of unneeded transports.

Thus I'm abit confused about Invasions and working out how many transports to throw at colonies. :notsure:

A lot depends on the improvements a planet has made. Planetary Defenses, for instance, will make it tougher to conquer a world, so you need more troops. It also depends on your relative military strength vs your opponent's.

While Bert is correct in a general sense, the figures Mark shows don't seem to show that the planet had much in the way of defense. Rolling 60/6 sounds like it should have produced a successful invasion with a loss of only .8K of his invaders. (Mark, I suspect those people figures were in M, not K).

Mark, if you have a saved game from just before the first invasion attempt Cari may be able to gleen some useful information from it.
