FWIW, I play Factorio and Satisfactory for different things. Factorio is where I go when I want to whip around quickly with my designs, flinging around blueprints and optimizing to my heart's desire. There's also that base/tower defense element that can be a different kind of thing compared to what you get with Satisfactory.

Satisfactory is a more meditative experience for me where I enjoy building and exploring within a beautiful, hand-crafted world. I find myself building with cosmetics more so in mind over optimization.

Sometimes I'm in the mood for one or the other, but they feel distinct enough for me to not substantially cannibalize my time. Though, mine is but one point of data!
