I saw this question posed on Mastodon. If you got lost in space and rescued by aliens who made you live in a simulation for the next 40 years based on a book, what would it be?
For me: The Great Gatsby. I would have to play the part of Nick and just get drunk all the time.
If it it was based on a book I happened to bring along for entertainment, there's a good chance it would a John Scalzi novel, which means it could be "Redshirts", and that would be pretty surreal.
Or some Ninja Turtles comics.
