I don't get the robots immiscibility with psionics theme. It seems to be just pointless flavor.
It's not "pointless flavour"- it's worldbuilding in service of developer expediency. The event chain text for the Psionic and Synthetic Ascensions are, presumably, simply incompatible with the text for Hive Minds. They'd have to double their work re-writing stuff to fit that fringe case.
Furthermore, there are probably balance concerns to take into consideration.
Making an in-universe explanation for why it's not available is better than it being purely mechanical in nature.
The Devs just are following a pretty common path within modern sci-fi where organic and synthetic life are set as thesis and antithesis where each of them contains some abilitys which are fundamentaly unique to each other.
For example in the famous Mass Effect series the so called "biotic abilitys" were exclusive to biological or at least partially organic creatures. Pure program/robot like beings like the Geth didnt had acess to it.
In Gene Roddenberrys Andromeda (yes I know how bad the last season was) we got a similar thing with the manouvering within the "slip stream" (a extreme fast FTL method where the pilot has to manouver among the natural streams within a special kind of hyperspace) was only possible for organics. Inorganic beings at least had to capture and and link themselfes to a biological brain to gain acess to some sort of special "intuition".
The Devs also I think want to build a world and a very loose lore for their universe at least.
And it is no bad thing to adapt this pretty common approach of organic vs synthetic dilemma.
As we dont need or want a total new reinvention of the wheel for the stellaris I think. We dont want the devs to write a new inovative sci-fi novel. So I think its nothing bad to implement the best parts of famous and known sci-fi elements.
Only thing bouthers me that the dont followed up Hegel and created even its just only oder special circumstances possibil. A SYNTHESIS.
Maybe we should have the devs settle this argument.
@Wiz @Zoft Do you guys at Paradox, does eusocial = hivemind or does eusocial =/= hivemind?
Though they probably won't answer until Monday.
I dont think the Devs should determine the ultimativ meaning of that work then to be honest both sides do have points but in the end it is you over/underestermine regular people.
And I am still thinking how I can pull of my Twelve Colonies/ Cylons playthrough ( mostly synthetic spiritual beings)
Maybe starting out with machinists and materialists and then switching my government ethic? Would that be even possible to that extent.
I am realy open to suggestion maybe some of the species which seem to be not playable are in fact doable with a bit RP and good amounf fantasy and imaginations and alot of micromanagment.
