I actually followed your walkthrough to have a real look at the game for the first time. I like what I see so far.
However, I noticed one thing. I got served with 5 or 6 very high quality planets around earth and I was baffled (one had 25 quality). So, after some turns I saved and restarted the game with the exact same parameters again and again. I noticed the amount and quality of the closest planet decreasing and varying, so I assume I just got very lucky in my very first map roll.
However, what I did not like is that I, as the human player, was always placed on exactly the same spot in the map, i.e. being the lower left area. I hope this gets randomized more in the final build.
