I actually haven't played any of those games but I'm surprised the author(s?) didn't mention any of Daniel Mullins' games. Pony Island, The Hex, and Inscryption are all really interesting "meta" games in the same vain as The Stanley Parable. Inscryption being the one that I feel functions the best out of the three as both a commentary on games as well as actual gameplay.

Author of the article here. I haven't played those games so I can't really comment on them :)

Highly recommended. Definitely seems like they'd be in your wheelhouse.

I apparently have Pony Island in my Steam library. Gonna take a look at it after dinner I guess. Thanks for the suggestion!

I'll second this; while I haven't played them myself, I've watched playthroughs of all three of them, and they really do an amazing job of blurring the line between the player's character and the real-life person playing the game. Combined with having some hidden secrets being only unlockable by doing real-world things outside the game, it's hard for to decide whether he's basically created a new art form that transcends the game genre or just has gotten everyone who's played the game essentially to join a sort of AR/roleplaying game of which his video games are just some of the pieces.
