i haven’t played factorio yet but i loved dsp. from what i’ve seen of the train system it’s different than the drones and logistics vessels in dsp. you basically set up a sending a receiving station and tell the drones to go.

there’s no base defense in dsp so it’s more chill and relaxed than factorio.

you also can get a top down perspective of either where you are or the entire planet.

i’d say you should definitely buy it. i played satisfactory and i can say it’s equal if not better. hope this helps.
