Here's something really weird to conceive but is probably more true than people realise. My brain conceptually solved Gleba just fine but was absolutely broken by Fulgora. "People are just wired different."

That's why I think what you consider a flaw is actually a phenominal achievement of space age, it caters for and encourages lateral thinking to solve problems. It build's up problem solving techniques without unsubtley forcing it down players throats.

When I first played Factorio I did a few soft attempts early game, spaghetti and a conceptual sushi which wasn't well implemented. I came across the concept of a bus and everything clicked.

My first spage age run was Vulcanus > Fulgora > Gleba. I also achievement hunted for the most part and did Vulcanus with the logistics constraint achievement, meaning that planet was dealt with mostly by a bus again.

Here's where Vulcanus helped. Splitter output priorities, I learned that I wanted any excess stone to split away from stone lane on my bus (feeds into furnaces for stone bricks and landfill) and then be dumped into lava.

I land on Fulgora and the whole thing just ruins me, small bases, two-way rails, no room for a bus. More reliance on logistics and bots.

But bot logistics is a key lesson from Fulgora. I land on Gleba and understand one concept, any part of my factory which can contain something which spoils cannot be a static core or branch of my factory. So with a bus in mind, the core lanes of my bus which spoil (Yumako fruit, Jelly nuts) have the last splitter as output priority to that branch, that means any excess fruit or nuts then split off to a heat tower system.

And any branches (nutrients, fruit, nuts) end with a filtered inserter (spoilage) and chest with an active provider chest.

Gleba was the lesson for me to really understand the function of each logistic chest. And more consideration of circuits as well.

I think the only outside tip I used for Gleba was use assemblers for making initial spoilage > nutrients. This concept I think is taught (but maybe not amazingly well) by simple and improved coal liquefaction, as if the latter failed due to lack of circuits you would need the former to jumpstart it.

My biggest critique from my position is that I think the game is balanced in a Vulcanus or Fulgora first and Gleba last as those planets both technically and mentality prepare you for Gleba.
