Bug Exploitation
Exploit a bug in the game and get more and more materials and gold every turn. (tested on the main release only... not the deluxe one.)
First you have to get two colonies(recruit settlers), transfer from one to the other(gold,metals, ect.) and set it on persistent, now keep trading every turn and it will say the next turn, you will be at -xxx, the next turn you will have the normal amount that you make, just go to the trade window and raise how much you made that turn (say your making 36 crops per turn and you have 50 crops, do the above and the next turn, raise
how much you're trading by 36 each turn...).
