I usually research the cheapest stuff first then sell it except for soldering techs currently I can have medium class starships warp 5 pyshionic missiles attack of 6 Some categories are maxed adv troop goes 28 spaces and carries 3k min research 1 per turn max research 4 per turn 2 harpoon III give me 14 attack the Ai seems to be less aggressive in building warships in patch then without patch or maybe cause I ran a 100% funding and buy a factory as soon as I acquire the planet. Why wait forever just rush a factory at beginning. Too expensive now manufacturing centers cost 2k each. Playing gigantic world with 9 brights. Bright is way too easy. so hurry it up with speedy ships.
