Factorio or Satisfactory: which kind of factory do you want to build?
The useful distinction is where you want to stand: above the production line, or inside it.

The first choice is perspective. Factorio presents an automated factory in a 2D world; Satisfactory puts you on the ground in a first-person, three-dimensional environment. Both turn raw materials into increasingly elaborate production chains. The way you read and move through those chains is different.
Choose Factorio for the overview
Factorio suits a player drawn to the factory as a connected system. A belt, an assembly line and a rail connection belong to the same expanding plan. Its developer also describes resource gathering, technology research, infrastructure and defending the factory against local creatures.
The tradeoff is that a bigger factory brings more dependencies. If the appeal is only making attractive buildings, the production and defence demands deserve a closer look before buying. Watch a section of ordinary play, rather than judging it only by an enormous finished factory.
Choose Satisfactory for a factory you inhabit
Satisfactory combines automation with exploration and combat on an alien planet. First-person construction makes vertical space part of the proposition: you can walk through the layout and build across multiple storeys. The official listing supports playing alone or with friends.
That physical scale is also the tradeoff. If you want a detached overview of the entire production system, first-person movement asks you to engage with space in a different way. The world and the journey through it are part of the experience, rather than just a surface underneath a diagram.
Decide together before a co-op purchase
Both PC listings include co-op, but that does not make them interchangeable. Ask your group whether the shared activity should be organising a production network or exploring and constructing within a 3D environment. A preference for one viewpoint is a useful decision, even when both games have the automation label.
This is a comparison of their documented design, not a hands-on verdict or a performance test. Check the current store requirements and multiplayer details for each player's setup.
