I love Planetbase for the future it is trying to represent. The simplest and most important aspect of colonization/city building that you have missed is our ability to expand on our own terms through the "FORCED" removal of our surrounding environment, i.e., earthmoving. We would not build around the mountains, but simply remove them to geometrically expand outward. We have been doing that for thousands of years. What would stop us in the future??? Create a robot or a machine for workers to use???

I thank you for your reply, and I am sorry for asserting you might be able to help. I have notified the developers directly on their website.

Auto-processor patents would be a great addition to the game as well. An auto-processor, which is very realistic, would need to be maintenanced by an engineer like a robot.

Try playing Outpost 2 to get some new tech ideas for Planetbase.

My reply was simply pointing you into the right direction; I'd have gladly helped if I could, so no need for apologises.

If/when you get a reply from the devs, perhaps you could share it here.
