What is your favorite setting in any fictional media? Games, books, movies, etc. What do you like about it?

I havent finished reading it yet but I really like the setting in A Psalm For The Wild Built by Becky Chambers. It's a wholesome and positive vision of a world that saw the error of its ways and decided to make amends and do things right, technologically, environmentally and socially. It gives me a sense of hope and pride in humanity which is an unusual thing to get from a setting rather than characters and story.

Also Solaris by Stanislaw Lem for blurring (or even erasing) the distinction between place and person and evoking a powerful sense of wonder and total 'alienness'. It was the last story I read that I was completely captivated by. Horrifying, beautiful and compelling.
