Looking for your favorite zero-player game recommendations

Hi fellow board gamers,

My wife (and her BF) sometimes play board games with me when they have time. We've played a lot of Pandemic and Scythe.

I've recently gotten into solo gaming (since they are busy upstairs playing their own sort of dexterity game), and I've really enjoyed the hobby and solving the solo puzzles that present themselves.

However, zero-player games have really caught my attention. I am interested in your personal recommendations. I love the concept of researching the games, the systems, reading the manual, buying the game, punching out the pieces, organizing it, putting it up on the shelf for everyone to see, to never playing it.

I imagine I will have to buy a back-up copy of the game, to preserve the shrink-wrap on at least one of my copies.

So please add to this thread your favorite zero-player games.
