After finishing the main game goals (delivery/challenges/gate) it would be great to have a mode that requires delivery of random modules similar to Shapez 2
Some observations:

• Generating interesting 3D shapes could be a harder problem than it seems. Devs played with this with odd module sizes for example. Making these kind of challenges in a procedural/generative way can be harder that expected (users could contribute their algorightms for this).
• Shapez 2 has logic gates and scanning funcionalities that lead to the creation of the MAM (Make Anything Machine: https://steamcommunity.com/sharedfiles/filedetails/?id=2301917022). Not sure if its withingthis game vision.
