> "this should scale to adventure games that humans enjoy playing"
I'm not sure that premise holds. Admittedly it's a different genre, but a lot of puzzle games are in exponential/NP-Hard/NP-Complete spaces. Tetris is an obvious example as a simple reduction of the packing problem. Humans very much enjoy playing those.
Even just restricting it to the genre of "adventure games", I'd be hesitant to say that there can't be games with very complex state spaces that humans enjoy playing. Maybe especially with "adventure games" where if the story and writing are interesting enough players will put up with a very wide variety of puzzles and exploration styles.
