yea i don't like campains in strategy games as much either. If this energy could be used in other aspects of gameplay it would be beneficial.
I think it would be cool if you could actualy control planets a little more instead of them simply being big spheres that look cool but cannot be manipulated. It would be awsome if there was an abuility to see your capital city or somthing and actualy build it up and try to siege other cities ect... just throwing it out there...
The Defensive base is a great idea
I would like a little more abuility to place objects without a restraint so i can actualy build defences and creat the thing that realy makes a strategy game appealing.
