That one's right up there with 'Shenmue.' In that it's enjoyable absurdism until you play the game, then it's brilliant parody.
I liked the Paperboy one they did.. Some are good, others are lame.. The Katamari one was kinda funny. They did it on a baseball field and one of the coaches of the little league got mad. They video taped it. Coach says it confuses the kids. Yeah this one was pretty funny too..
That one was good but my favorite is still the Tetris one. And I liked the part in the Luigi's Mansion one where the woman asked if he was a little ******ed.
I love the part in the ice cream shop (or what ever it is) when he slips past the girl and run into the back room and she looks up all confused.
