Frankly, Machine Empires need two things to become more than an exercise in masochism - an increased pop build speed and the ability to take advantage of commerce. It makes no sense that they can't in the first place
HONESTLY, why wasn't trade a thing of gestalts except rebranded and give you different things? like a hive network, that when utilized either creates energy credits from more efficiently utilizing resources. this could be changed to make minerals at half value(maybe quarter), or unity, as the network is more careful about cohesion. wish trade could be somewhat planet based, so you could use it to create amenities. if more complicated systems could have been done, trade could have simply increased planet stability and lowered deviancy from the increased connections.
