I have been playing for about 3 weeks now and have a strategy question. I know I automatically will go to war with any civ whose ship I destroy, but if a colony ship, for example, is in my sector, (obviously trying to get to "my" planets), I have been destroying them. Eventually, I am at war with someone. Some back off and offer a peace treaty, but others keep coming. I don't go into their boundaries. Could someone comment on this strategy. Should I protect the planets I intend to colonize with preemptive strikes early in the game, or just let them encroach (then wait for an opportunity to take the planet once I have the invasion techs)? Please excuse the awkwardness of the question and be nice....I am a newbie. By the way...this is the best space sim I have EVER played. I congratulate the developers and every team member!
