Factorio is (kind of) infinitely scalable. There is no max map size, and the game engine's performance is so incredibly good that it can support absolutely insanely massive factories. You can go as big as you can imagine, and the game will keep up.

It's also ridiculously stable, in the ~thousand hours I've played I've never had a crash or a game breaking bug.

Meanwhile satisfactory puts you on a fixed-size map and will slow down to a crawl once you build too much. This limits a lot of the things you can do in the game.
