Time spent on the galaxy map could take mere seconds before another attack is launched at you, or it could take minutes to hours. It's a guessing game, "Where will the enemy strike next, and when? And with what?" If it takes hours though before you see any sort of combat, you clearly are a defensive player. I will have ten minute gap beetween copbat, usless I've had a bad day a just need to kill. Impossible. Noone is going to be able to gather enough forces to attack every 10 minutes. Maybe at the very end of the game perhaps (when the opposition only has a few planets under his/her control left), but not in the middle, and certaintly not in the beginning. Spread out your forces too thin too quickly, and you will lose.
