1 how long does it take you to transfer resources. most of my colonies are within 2 slots of each other and with pulse drive 5 it takes 53 min to get resources to my home planet.
2 I have a hydrogen planet in 15. Y because I need more hydro for tech.
3 I personally dont build more than 5 sats to power my colonies. (this makes them a less tempting target for my enemies.)
I hit 1 planet just because it had 25 sats around it. sent in the recyclers to harvest. And I know I disrupted him mines
that was the fun part.
4 is the planet a fire base (strike base) IE I move my my ships there so that I can hit a person in the next system over and instead of having 4 hours to fleet and resource save now he has 1 hour.
lastly i dont keep colonies under 200 fields - y pour tons of resources at a planet that can not return the investment. (Exception to this is the fire base, I dont really care how big it is I wont keep it after the war is over.)
