On point 5, if I had to describe the game to anyone it would be Fast Travel: The Game. It's not a great feeling when you travel between planets in different systems by simply clicking through a few overmaps.

The uninteresting way you can leave a planet's gravity well, and zip between places lightyears apart is a bit disheartening.

I'm hoping the enterprising mod community will be able to fix this game, adding in a real economy and more travel management.
I wasn't expecting a hard sci-fi game, but I also wasn't expecting something seemingly uninterested in the genre.
