Please forgive me for not reading all the 650 comments, so some of these might have been mentioned already
Here we go:
- In some lists, there is a clear "default" action. This should be accessible by a double-click. For example, loading a saved game, or "go to" in the turn event log. I usually double-click those, wait a second, nothing happens, and then I remember I have to use the button...
- When I load a saved game, I always get the report screen, the tech screen and one colony screen (I suppose my homeworld). The first two are ok (to remember and re-check the place where I left). The planet view, however, doesn't make any sense and should be left out IMO. If I hadn't saved my game at that point, I wouldn't have checked this planet either (unless something was completed this turn).
- I would like to see an area-of-effect circle BEFORE creating a starbase. This way, I would not have to guess when I want to choose the right place for a new base. How exactly this should work out GUI-wise, no idea.... maybe the circle could be around constructors all the time, or appear on first click on "construct" while a second click actually builds the thing .... or add a toggle button in a free spot somewhere....
- The area-of-effect discs of bases are sometimes very hard to see. Maybe a solid border around the transparent disc could help?
- Enemy ships in sensor range should have a highly visible marker (like a red circle). I think it's realistic that the emperor does not scan the space map himself, but gets informed of the nasties
- Not quite sure if this still falls into the "minor things" category, but I miss the ability to move a spaceship component after I have placed it, i.e. to re-attach it to another mount point. Maybe it could be detached with a right-click or double-click?
After all these suggestions, compliments on a very nice game.... well done
