One of the things I found lacking in GC2 was that any time you reloaded/restarted a game you had to re-establish so many settings, such as:
The zoom depth and view angle of your galaxy
The selection of which "Civilization Manager" you were viewing (F6) and which list item you had your colonies sorted on (i.e., colony name, planet quality, population, et al.).
Minimap zoom factor
I think the number of environmental variables saved should be increased.
Give me more time to review GC2 play and I will come up with more.
