I am thoroughly convinced everything level 16 and above is literally impossible on blind mode. There is no logistical possibility of outmatching their base production of ships, so what chance do I have? This has gotten me very frustrated, because I've beaten the game multiple times and loved it, but have found that on these levels on this difficulty there is no possibility of winning, I am convinced. For instance, on the Awakening, even if I do control every planet as a result of bum-rushing them for captures, I am still outproduced and outnumbered on each planet, so I am stuck with my manufacturing and the mother ship can just churn out warships like nothing. It's insane!
That said, I loved everything else about the game. I would definitely like to see a sequel, perhaps with construction options for colonized planets or for different types of warships.
