Satisfactory feels a lot more like other open world games. Not that it’s actually comparable to skyrim, but it is kinda shifted in that direction. There is value to go exploring and find different things or useful areas which can help you progress. Satisfactory has a huge map with a to of beautiful places to explore and build on, but the map is not random generated, so the replayability is a bit limited for the base game.
Satisfactory is a lot slower on progress and never reaches the “endgame” of Factorio, i.e. you won’t get a swarm of drones and slap down huge blueprints to harvest whole areas and the factory will probably not be as “refined” and structured. You get small blueprints so you can easily make parts of production lines.
An obvious point is also that Satisfactory is 3D. So you have a whole extra dimension to use for production lines, and the game features several components which allows you to make use of walls, ceilings and additional platform levels to refine your lines.
But even though the game has very different visuals and several different aspects, they hit that same sense of satisfaction with constructing systems with maximum output and see things work. I highly recommend trying it, although you might want to consider waiting for the full release (which is TBA, but speculated to be “soon”).
