After playing the space exploration for 230 hours, I think I am starting to understand the difference between "building a small company" and "building the Amazon"

@Jens_Rasmussen
Normal factorio run at my ability level:
It takes about 20h
You have to change mines once
most early research can be cheezed
In the end, you really don't need to construct anything that needs more then 5 resources.
No circuits needed

Space exploration:
230h in, and I am still in the mid game.
I had to learn circuits, since the tequirements for varried cargo on spaceships cannot be done simply.
I had to change source of every resource many times, making legacy infrastructure into a huge problem
I am right now on 4th reconstruction of my space base, since the complexity keeps on growing (I heard, that endgame might require 16 resources per product)
I had to manage liquids efficiently, something I had no idea could happen in Original

So, in short, the scale required to get where I am NOW is MANY times bigger, and any infrastructure imperfections WILL bite you in the ass later.
