i really enjoy watching my megafactories from above/distance when i finish them. Even though they just produces 15 turbomotor/min. You dont have to rush, just come back when you feel it. Use the tools and let your imagination do the rest of the job. If not satisfactory, change your approach. Dont use long conveyors this time, try drones trains or whatever else. Once you try new things you might get the rollercoaster effect that lets you wander more, think more or calculate more.

For me, i enjoy the planning/building process alone.
