synthetic races have a mostly global population cap. i think there are some planetary improvements that are supposed to increase population cap only for that planet other then that it is global by tech tree
Thats the matrix building which is individual per planet. After that, its all global.
Also do you think the cybernetic trait is overpowered? I am able to just spew out legions of populations with my factory worlds. I am literally growing populations faster than I can find planets to colonize.
Mid to late game it can be very powerful. Still a debate over the OPness. You need some power to help make the race stand out but is it too much? Maybe.
