The Outer Worlds is in the same bucket as Starfield, but with fewer space-specific elements. Starfield has light space flight combat, though it’s not very sophisticated, more of a minigame. And Starfield has zero-G FPS bits. Oh, yeah, and you mention The Outer Worlds having fixed gravity – Starfield does have variable gravity. But if you removed that, you could make either Starfield or The Outer Worlds not set in space and it’d basically play the same way. Maybe you’d have to come up with some alternate explanation for alien animals and flora, like bioengineering or something, but lots of games have done that.
