The crazy thing is that with a better type of bonus ship (sieges are off the menu again, great against forts, terrible against everything else) I could have had a slim chance of victory without so much cheese. There were 5 V fabricators, 2 core fabricators, a IV factory, an artillery golem, an ars, and most importantly an armored golem on one planet. If I took just that one planet instead of the two I took (three if you count popping the warp gate) I could have maybe won with some trickery...
well, before 5.071 at least.
