The homesystem is the most important one in any game so it needs to be really good to give you a fair chance of a good start. I usually start three to four times until I am satisfied. Right now this is quite tedious as I always have to end the game and then go back to the main menu and even to reset all my chosen gaming options as they disappear and are not saved, at least the AI factions are not. I would prefer to be able to restart the game to get a new galaxy after I have started the game, say in first turn as it was done in Civ4. That would be so much quicker and less annoying.
