If the franchise is more than five years old and still being made - then there is a themed Monopoly for it.
I had no idea Pokemon was that old? Yeah, rule 231 in action; Pokemon Monopoly has been out for a while.

The Expanse is getting a fourth series can we count on rule 231? A Monopoly version in time for Christmas?
