Please tell me if I have this right. I've always heard something about "trade ports make money based on the longest trade route." Now, who the heck knows how to interpret this, but I always figured I should make the distance between trade ports as long as possible. To do this, I select the two (and only 2) planets in my empire that are furthest from each other in terms of phase jumps, and pack them with as many trade ports as I can (usually 2 or 3 on both planets). I put no trade ports at any other planets, because I figure that's "shortening the trade route," and I want to keep the longest trade route possible, right?
However, I'm not sure I understand this correctly. I play people online who seem to spam trade ports willy nilly at many planets. At first I'd chuckle to myself, thinking they didn't understand trade ports. However, perhaps I don't understand them?
Is my understanding correct or incorrect? Do you make more money by spamming trade ports everywhere, or should you just pick two worlds distant from each other, and stick trade ports on those?
Thanks.
