Comar,
I plan on examining it over the next few days. The size of gas planets is the main advantage, but the quad I am in now is averaging less than 0.5 gas planets (of any atmosphere) per system. I've explored 15-16 systems and have 6 planets in 4 systems, with only 2 (homeworld and 1 other) breathable. Now I have meet 1 other empire ( a neutral, rock dweller) and they are 3 places in front of me. While they are extremely friendly and willing to enter in to a T&R treaty, I can not get them to trade me 1 colony ship for anything or combination of anything (I always stop short of giving dealing in planets). I guess I have to aquire it or the tech from some other means
.
The above is not meant to be any kind of complaint, in fact this will probably be the most challenging/fun SE4 game I've played yet. Luckily there is no other AI close and there is only one route into the 15 systems I've explored. I'll keep y'all posted.
