In many such games where you get to create a random galaxy/map, one feature that absolutely needs to exist is a button or key combination that will re-do or re-create the galaxy/map using the same user defined settings so youre not forced to go back through the menus again just to get a new map. Gal Civ 2 let you do that and it saved lots and lots of time as the random galaxy/map generators have a tendency of making very poor maps most of the time. Civilization 5 if I recall did not have such a feature and it was an insane chore to keep going through the menus just to get a fun well balanced map.
