My goodness! Is this truly and issue?
Personally, I rather enjoy setting all those parameters, but then I only start a new game a couple times a month. In fact, though I use the same theme for my empire each game, I doubt you could find two that are totally identical. By making small variations I've found some wonderful little, hidden niches where you can get more bang for the buck. And, as I said, its fun, too!
