I played The Beginner's Guide over the weekend and while it was definitely more of a narrated presentation, rather than a game, it was really sweet and wonderfully thought provoking. :(
This was like a gut to the punch at first, since your entire image of Coda is from the Narrator's POV and his interpretation of the games.
And then you get more of Coda's explicit thoughts on things and it get way more heartbreaking how your personal hangups and projections can fuck up a relationship so badly. :( Loved it.
