-control of one of the workers and place whatever blocks so you can make stuff like pixel art or whatever you desire.(maybe first/thirdperson mode? )
-wiring similar to redstone to make killing machines and defense and whatnot.
-if KS reaches a certain amount, you can reach eras like steam and industrial through time so you can get stuff like muskets and other technological things.
Lastly: TRAINS AND BOATS! You could craft and make train tracks and have them transport blocks and people. And if multiplayer happens, you could trade with other cities/people. Boats could do the same but over water.
OH and what will the models be made in? You’re own tools provided to us or we use our own? I don’t want to buy Qubicle Contructor as SLAB6 has always been faithful to me D:
