This is... not what I expected.
It's an interesting exploration of minimalism that raises some interesting questions about game design. How much rules does a game need? What is the expected amount of homebrewing in a game? Is it still the same game is most of the gameplay is homebrewed? What is a game?
However, I can't shake off the feeling that if I were to buy this (I haven't; I've received this in a bundle), I would probably be disappoined.
Added: If anyone has doubts, like I did: these are not games with 2 verbs (i.e. 2 actions), these are literally games with 2 words (+ tagline and images). They're conceptually interesting, they're well designed, beautiful and high quality. Though-provoking and available in different formats.
But the 2-word format has some inherent limitations, so you'd need to come up with some rulings / house rules if you want to play these games.
