Hi, enjoying your game immensely over here.
My humble tweak suggestion is to
add a quick-start option for new games:
When starting such a game, available planets (some, many or all) would already be colonized somewhat evenly by the powers (though some might have been luckier than others), all the powers would have some of the more basic techs already researched and military might (a few defenders perhaps) even. None of the powers would be at war or trading amongst themselves --> A neutral start.
I imagine it doesn't even have to be difficult to implement; simply have ALL galactic powers run on AI for, say 50 turns or so, in the background before player finishes loading the game. With the exception of Warfare being forbidden and no trading, though there are sure to be many more complications.
And it could even make the game feel a bit more like GalCiv
-2-, historically speaking!
(The reason for my suggestion is that the Gold Rush era at the beginning of each game often annoys me, I'm a sore loser when it comes to colonizing planets!

Oh, and I know my nickname is cool.)
