Funnily enough at higher difficulties the AI has been reported as being quite improved. It'll deliberately seize chokepoints, launch coordinated wars on threats, and generally give you a harder time of things and keep you on your toes. A higher difficulty with scaling difficulty on can pull ahead of the player quite well long before the AI bonus mid-game peak.
I think they optimized the AI to manage itself well on higher difficulties, meaning on lower difficulties it can sometimes explode in on itself.
Although it'd be nice to be able to mix up the AI difficulty for different empires within a game, pick a range that AI empires get sorted into. Would be nice for some AI empires to explode in on themselves regardless since not every empire should be a success, rather than either all empires being dumdum or all empires being exponential boomboom.
I really doubt the AI's any different, it's probably just the nature of
its bonuses on higher difficulties. There's a flat Stability bonus, cheap/free resettlement, and naturally a resource bonus. Considering that serious overcrowding is naturally mitigated now, I'm more surprised that the AI is still able to have revolts at all.
(Unless it gets vassalized by a player, of course, which immediately strips all of its bonuses... That must be crippling to an established empire on later difficulties, but I only play Captain)
As a side note, I´m really enjoying the machine intelligence I cooked up. Basic setup is a quickly replicating machine intelligence which starts in a ruined ringworld.
My headcanon is that they´re emergent programming from the ringworld´s maintenance system subroutines. As such, their goals are to repair the ringworld and get up and running, and build tall instead of wide. Unless there are particular strategic resources to be taken from them, neighbouring organic empires would be made into tributaries rather than conquered outright.
Nice! I also just started a MI on a ruined ringworld. It's an otherwise default Tebrid Homolog because, well... I like exploiting broken mechanics before they get patched, and I've never given Driven Assimilators a proper try before. Seems like an excellent time for it!
And what luck, I spawned next door to a Federation :O Perfect for what I have in mind: A cluster of three homeworlds belonging to different "empires". They're mostly boxed in now, and I predict they're going to survive till the end of the game~
The plan is to keep them around and independent, but periodically raiding them for pops via Nihilistic Acquisition. By the endgame- heck, by the midgame they'll be my primary source of pops. Plus all that unity and society research I guess! I just have to protect them from the rest of the galaxy. I don't know how far I'll go with it though, I mostly just want to play with the loophole a bit. I'm not really invested in playing Borg.
Hm, rogue servitors can get nihilistic acquisition too... Oh but that'd be a heck of a challenge mode since the biotrophies would just prevent drones from being constructed
I guess its a fine time to try authoritarian xenophiles too (again picking up nihilistic acquisition). Can't enslave species, but can technically use that wonky 40% slavery civic. Or play it nice with social welfare.
