Mountain is the polar opposite of Starfield.

In Starfield, the universe is yours to explore and interact with immense possibility.

In Mountain, nothing is yours, you’re looking at a lone mountain in space, and you can barely interact with anything. 

 @Chris Trottier If I wanted to stare at a lonely mountain, I'd rather just go read The Hobbit. 

 @dd68da48 What? I don’t understand – the Hobbit is something you read.
