I always get owned by the AI on captain difficulty. I will have like my mighty fleet of 10k and try to build a secondary fleet but then some racist alien empire will declare war then I will defeat their initial invasion fleet and rejoice only to find out they have like 3-4 more fleets on the way wrecking my star fortresses and pushing me back to my home system. Any tips? Maybe my planet management sucks. I have also found that I will always have surplus energy credits or food but then lack half the other resources like alloys or the orange stuff or vice versa. It's like the god damn Dominion war every game. My fleets gets wrecked and I can never build fast enough to have several 10k+ fleets or one mighty 20-30k fleet. I have done research and found out the some players manage to get huge armadas with like 500k?! HOW do you do that? Any advice even if it is a few words is appreciated.
