You know I almost want to call this a bug. I notice that on all difficulty levels, the AI just isn't very good at building ships. Even if all else is equal, I find my ships will always beat theirs one on one. Even if they're the same class.
Anyways, the strategy part of this post. I notice that if you concentrate on building larger ships, with some tricked-out smalls just for area defense, the AI simply can't counter it. You'll have situations where one of your cruisers beats the pulp out of their fighter hordes. Again and again and again.
Does anyone else think the AI should put more weight on ship class rather then cumulative attack/defense rating when building their ships? Or making the decision to go to war?
