By only major gripe with this game is the military rating. It continues to play havoc with good games. In a recent game on Painful, the Alterians had a military rating of 185 vs my rating of 85 and declared war. But the AI didn't seem to notice that since we were the two major players, all my defenses were set to counter his. I had driver weapons and shields defenses. He had beam weapons and shield defenses. In the war that followed, he lost 170 ships, I lost 2. By the end, he had developed some armor, but by then he didn't have enough planets to produce them in mass. Since I didn't have to produce more ships, I could produce transports in mass. I think I took 8 planets in the first 6 weeks. Within 25 weeks he surrendered (to me oddly enough).
While the military rating is important, unlike tech or economy, it's relative to the race you're looking at. I would like to see implemented a way for the AI to look at it's relative strength when looking who to pick on to keep itself from doing really dumb things like it tried in my last game.
BTW, I was trying for a tech victory and was happy to just sit back and grow/research.
