We are told that basically having too many colonies can cause you to go broke and that it is not a good idea to colonize unhabitable planets. (I would think that such advice would apply more to the early and middle part of the game, and that having more colonies in the end game when you have more options for building profitable colonies would be an advantage in the end game, but that is another strategy question for later.) Anyway, in my current game, I am at war with an alien who has a swarm of colonies, but on inhabitable planets that have been partially reduced...toxic, barren, heavy gravity. These colonies are very non-productive, some with 0%, a few with 50% production. In one part of the galaxy he had 7 colonies only one of which was normal, which I've captured. Now, I don't want to take over the other 6 colonies on bad planets because they might run me broke, and yet I don't want to leave them in his hands because as he develops tech they might give him bases and production to bite my butt later on. In other games you had the option of destroying a city you didn't watn so nobody else could use it...but in DA there doesn't seem to be an option to destroy a planet. How are the winning game players dealing with this kind of problem? Thanks for replies.
