I too am having difficulty with this level (as much as I hate to admit it) and I've been playing this game for a while. Paul, you say get dreadnaughts ASAP, butalso get Eyes of the Universe. Sensors and such are not on the path to dreadnought. But if I don't get sensors I can only see the transports when they are AT MY PLANET. So no time to make corvettes or anything. And even if I DO make corvettes, the AIs transports WINS THE BATTLE half the time! So how do you make corvettes that can beat transports? Since the AI gets ALL the resources to mine, including a military resource, I don't see how a corvette will win the game for you.
Also, because there is NO trade, my economy lags so far behind the AI that I can never keep up. If I do trade, the Avatar just sits there destroying the trade ships until the trade route disappears.
I usually take 5 planets in the opening, but never am able to get the economy going to even get to battleship, much less dreadnought. In this last game 3 minor races showed up so that helped me becuase I could trade techs with them, but not for long! The AI took them down fast. Then invaded me using gas warfare taking out two of my most populated planets.
Is there any other tip you can think of that helps on this level?
My start is to rush build a colony ship to get as many planets as possible. Maybe next time I'll just set military to 100% and see how many planets I get that way. But even when I get 5 planets, within a few turns has 8 or more and population and production are screaming. I cannot keep up so any help is appreciated.
