Cyberpunk is part of the cyberpunk subgenre and has a premade main character.

Fallout is a post apocalyptic game set in a retro futuristic universe.

Outer Worlds is not post apocalyptic but being in barren planets in the frontier gives it a much more similar vibe. It’s basically a spiritual successor to Fallout that falls short in a lot of aspects.

I don’t think Outer Worlds is bad but if they couldn’t live up to New Vegas they shouldn’t have set the expectations they did.
