* You can choose landing spots on a planet or fast travel to an existing one.

* `New Atlantis` is the biggest city Bethesda ever created. There are more cities:
* Akila city: Western style. Looked like RDR2.
* Cydonia city: Mining city built for resources.
* Neon: Known as *Pleasure city*. Cyberpunk style.
* There is a *mythical* group called Constellation. They are the last explorers of humanity and are looking for answers to long lasting humanity's questions. Your main story revolves around them I think.
