Mini Review after my first campaign:
Senate says "NO to war" sucked when they did it in civ, and it sucks here too.
Diplomacy is excellent and colorful. One of the races, the honorable ones, were the only guys ahead of me. The senate kept on telling me I couldn't blow them up, so I waited. Then one of the lesser races came to me asking for help, saying the honorable ones were killing them. I offered an alliance. They accepted. When they came to ask me to honor that alliance, the senate couldn't say no.
At first it was back and forth, but I had a tech advantage. After some warring and they lost a few planets, I get "This war is draining both of us. Lets make peace." To heck with that.
Eventually, my newest warship hit the frontlines. The damned thing had enough beams to take out an entire enemy fleet by itself. Now I get the same call for peace, only this time it's phrased "OK, ok, OK!! You WIN already! What do we have to do for peace? Anything!". Nice to finally seem some life in a diplomatic situation.
Didn't play much with the ship builder. Too time consuming for a first play through. It does seem to have a bit of a lack of real combat options. None of the wacky devices from MOO2, just your basic beam, missile, cannon and their defenses.
