Looking for Survival PC Game?

Definitely I'm just looking for a PC game which should fulfill the following requirements. I want a game like ARK or The ForesT. By steering a figure and surviving with simple materials. I start small with nothing like in ark and then develop myself. ARK is Multiplayer and The Forest too remote. I can't put it in words. It's supposed to be a mess. Minecraft Bite Something The Forest and ARK. Survive and build a base, etc.

Conan Exiles

Conan Exiles, Atlas.

Subnautica, Rust, …

Is not that also multiplayer? Or does it make sense solo?

Yes saubnautica would not be my environment type (under water)

Can you play alone like Ark? It feels more like an RPG then.
