I'm not thinking 'realism' I'm thinking "reduce the micromanagement."
Seriously, the yor used to be my favorite race in galciv 2 because you could just plop down one economic building per planet and focus on spamming ships after that. Now you need to micromanage the growth of every single planet and it doubles the number of things you need to do to prepare a planetary invasion.
Oh i see, its a game balance verses micromanagement issue.
I really think game balance should take priority though.,, because it is a complex strategy game by design, so micromanagement goes hand in hand with that.
So really it all comes back to how smoothly you can get through the micromanagement with the nature of the UI,,,,, and there is no shortage of debate on the state of the UI for galciv3! lol
