I'd like to propose adding more, or even some "obstacles" on the starmap, such as an asteroid field that blocks, or slows down ship movements through it.
The AI already has to cope with obstacles on the map, such as suns and planets, so it should be able to cope with some "walls" like asteroid fields. I don't want the map to be cluttered by such, but imagine a system inside such an asteroid belt, only accessible if you move through the belt at 1 parsec/turn. Players could use such obstacles as part of their border, given some more complexity to the choice of where to place military forces.
It could be toggable on the galaxy creation screen!

This may already have been proposed, but there should be an option to not make the game stop when you have won. It's annoying sometimes to "win by accident" through influence, just when you were so lucking forward to annihilating that last planet of the enemy, or just get some techs to create cool fleets. Of course influence win is toggable, but still the player should be able to choose whether he just wants to daddle on after he's won.

The "new level of espionage" screens really need a "done" button. In like 3/4 of the cases I click on other things so fast the screen disappears before I even got a chance to look at it.

I know many tech descriptions are still missing, but for those that are complete, I'm hoping they will get longer, with more technical details, more like GalCiv 1. Don't get me wrong, the humor is great, but humor with more details would be better.
5)
The AI in the United Planets sessions tends to make arbitrary decisions, for example the last surviving AI did not vote for sharing 8 technologies among all races, even when I was vastly technologically superior. I know the screen itself is not finished yet (graphics etc), just hoping the AI will actually make decisions that are beneficial to itself

Something I already noticed in GalCiv 1: In UP sessions when you have a choice how many techs should be shared, or such choices, often "D: None" gets chosen, because all other civilizations chose different options, (e.g. one chose 8, one chose 6, one chose 4). Sometimes strange to think that ultimately none gets shared, even if all agreed to share some. Maybe in such situations the choices should be "8 or less", "6 or less" etc.
