The Page I Didn't Write is a one player, one page, letter writing game about not writing a letter.
There's a lot of contradiction in there, but the basics of play are that you struggle to write a letter, the dice decide whether you get to say the things you want to say, and at the end there's a 50% chance you just destroy the letter.
I think this is a game that's better read than played. It has a lovely layout and structure, and it really does encapsulate the frustration of struggling to say something true. But if you get frustrated already by that kind of thing, having the dice add more frustration may not be an ideal experience.
Overall, I don't think a lot of letter-writing games include revision as part of their process, and if you're interested in letter-writing games, I would definitely recommend checking this one out.
