Earthbound/Mother creator planning to play through Mother 3 'as a player'

Believe it or not, it sounds like Shigesato Itoi, the creator of Mother/Earthbound, has never played through the finished version of Mother 3. He's certainly had is part in developing every single aspect of the game, but apparently he's never sat down to play through the final retail version. He's planning to change that, as Itoi recently took to Twitter to announce he'll be playing through as a player for the first time. I hope he chronicles his adventures!
