I wish you'd explain why this made you angry, because not playing this incredibly splendid atmosphere of a game just because of some fourth wall breaking at the beginning is an incredibly sad reason to devoid yourself of the experience.
With the comment as bare as it is, it just comes off as a flat-out insult to the creator and it's fans.
Gyahaha Fubaka, this is almost exactly the same kind of thing you- wait that's kind of a spoiler.
Anyway, in theory, I don't particularly like the idea of an author putting herself/himself into a game, especially expressing the concept of being some kind of god who made this world which is despite that an imperfect world yadayada, but how acceptable that is tends to depend on the arrogance or lack thereof of the creator combined with the quality of the actual game. And really, how one judges a game should really depend solely on the game itself, as, like someone has once expressed, "Love the art, not the artist."
