I think it’s less about making a choice between one and the other, and more about committing to the features. Satisfactory could easily have a decent combat component to it (more specifically, the factorial model of
automated combat makes perfect sense for a factory game, and 3D tower defense games are quite viable).
The problem with Satisfactory is they half-assed it — they didn’t commit to adding combat, they just tossed it in because why not. There’s nothing really stopping them from layering on combat mechanics without disrupting their current gameplay… they just need to actually do the full job, or not at all.
It’s not even unreasonable, as currently the game has no real driver for optimizing base layout or production rates beyond your personal interest in doing so.
Power, per your description, is the same; if you just toss it in because why not, it adds nothing to the game, and usually detracts from it instead. Ultimately any additional mechanic needs to be “worth its weight”, and should either alter your interaction with existing mechanics, or enhance those interactions.
Simply targeting “more simulation” isn’t sufficient justification on its own
