So for example, I just completed my Kir’ko/Promethean game. I followed what I consider to be my usual pattern: Expand aggressively, spending just enough on military to keep my main hero (and shortly, second hero) out clearing neutrals and dig sites while pushing Colonizers almost literally as quickly as I can afford them.
This game: I founded my fourth core colony on turn 23. I believe one of those was my “natural neutral” which I bought as soon as I had the influence, which is generally how I roll.
Once I have my immediate area colonized – aka I bump up against natural or rival borders and don’t feel good about expanding any further without exposing myself to a sneaky early attack by a rival – I blow my cosmite on whatever the best dudes I can afford is to flesh out a second/third/fourth stack.
This game: As soon as I got the Promethean doctrine that makes Promethean dudes cheaper, I whipped out a bunch of Purifiers with the madly overpowered Purification Field mod (once per battle: free action, heal 15 and remove all status effects from this or adjacent unit). Kir’ko Purifiers are awesome! Plasma Smog just wrecks dudes.
Then there’s the second wave of colonization now that I have a military the AI is cautious of before it starts looking for someone to shove. These secondary colonies might never build a single unit, depending on terrain. But they’re crucial to keep my economy rolling as I get to dropping a modded T2 or two out of my primary production colony every turn and start in on T3s.
This game: Yeah, colonies 4-7 were almost exclusively for econ. So much econ, though! I was rich as hell this whole game, to the point that my primary production colony (the first one I founded after my capital, this time, which had a nice landmark and a nice dungeon) got all its buildings rush-bought so it could keep supplying Purifiers and Aegis Tanks to the front line every turn.
Side notes: Aegis Tanks are specialists! So they get the bonuses from the non-elite production sector specialization. So good. Also Transcendents are fabulous and don’t really need any mods to shine, so I had my capital pumping them out when it wasn’t busy with colonizers. Don’t forget to mix them in with your naval armies with the Kir’ko!
Anyway, from there everything depends on who declares on whom, where the breakpoints are in terms of getting fancy new tech online, and which victory I’m pursuing.
This game: The first foolish AI declared on me about when I expected it to, so I was good and prepared to pivot from clearing neutrals to murdering Syndicate. Yeah, she didn’t stand much chance. After that it was just a matter of rolling my tidal wave of bugs over everything in their path. Won a pretty uncontested Empire victory (for deleting two enemy Syndicate commanders) on turn 56. Kir’ko leveled from 4 to 10, lol.
I love Star Empire.
