Well, that made sense and worked like a charm. One turn I was losing money.. the next I was magically well into the black. And then imagine my surprise several turns later when I discover you cannot bomb a planet from orbit. "what? I have to develop troops??"
So, keep my homeworld at a minimum of around 2.5 Bil, colonize with 500 mil ships to each world. At 500 mil, as I assume, the taxation will help balance out the support costs assuming it doesn't turn a profit. And it's going to cost me, that's a general given, within the first game year once colonies are up enough to be profitable. Well, I'll give it a try here in a few hours when I have a chance to play next. Thanks for the info. </p
I'm going to apologize if this repeats any information that I may have missed in my brief search on the forums. I am in the process of learning and getting a grasp on the play strategy of GalCiv 2: DL/DA/TA I come from a diverse background of Stars! Supernova, Space Empires 3, 4 and 5, Sword of the Stars and Master of Orion 1 and 2. Each of the games has a variety of conditions to keep in mind when you develop or colonize your worlds.
