Hi,

you can generate an infinite amount of resources when you permanently colonize the same planet over and over again with the Gigalord. When colonizing a planet you get 2.5k of every resource, no matter which colonisation ship is used. But the Gigalord stays on the planet and if you only build until the spire and fly back to the orbit of the planet you are left with a lot of resources.

Calculation:
You get 2500 metal, 2500 minerals and 2500 vespene in the moment the Gigalord colonizes a planet.
Building the Incubator to lvl 3 and then spire to lvl 1 costs:
Incubator 1:  50 metal, 5 minerals
Incubator 2: 80 metal, 8 minerals
Incubator 3: 128 metal, 13 minerals
Spire 1: 800 metal, 100 minerals and 250 vespene

Further you have flight costs of 680 vespene to move the Gigalord from Orbit down to planet and back up.

Finally you generated:
2500 - 50 - 80 - 128 - 800 = 1442 metal
2500 - 5 - 8 - 13 - 100 = 2374 minerals
2500 - 250 - 680 = 1570 vespene

You can do this over and over again on the same planet with as many slots you like.
It takes me 7.5 minutes for 1 flight. This means a total of roughly 20 minutes including building the necessary buildings to get the Gigalord back up. So I can do this 3x per hour which means I get per hour per Gigalord and planet:
1442 * 3 = 4326 metal
2374 * 3 = 7122 minerals
1570 * 3 = 4710 vespene

This is basically the production of a semi-developed planet and if someone gets his Gigalord early it's even more than a production of his planet. (In late game it's probably not enough anymore to cope with fully developed planets.)

Further if you use 30 seconds more and move the Gigalord from one planet to the next planet then you also can collect the resources that spawn on every planet every 6 hours which would increase the output for each planet by roughly x1.5 to x2.0 if the person is lucky.

I think all colonisation ships that stay on the object after colonisation should not grant resources because this is exploitable.

you also forgot to factor in the distance to the next planet and if you are going from planet to planet you cant go back to one you have been to for the extra bonus resources until its been the full time for them to respawn. i have done this looking for gas planets in uncharted galaxy's and its a big chunk of gas moving from galaxy to galaxy so in turn there is a loss in gas to equal out the most of the gain.

yes, you're right. I forgot the factor of moving over to the next planet which currently amounts to 3k vespene for me.
This still could lead to a small increase of vespene if you find more then 1500 on the next planet. Also you definetely can increase metal and mineral income of this way a lot by paying very little vespene.

but still Tii you have to give up a planet to do this and is it really worth all the effort to not have that constant production from that planet and have to do nothing to get it

honestly i think its a good balance for the gas guzzler till you find the perfect planet

oh yeah dont forget to factor in the fact it costs -1000 energy when its sitting around doing nothing and on top of that the almost 16k points that wont fit into the hide tech

I already earned multiple ten-thousands of resources by this by trying to simply get enough free fields for building on the planet that I try to colonize.

The resources which you get colonizing a new planet with Gigalord is not a bug.
