Itadaki Street DS apparently didn't have enough characters to choose from-- the entire Mario and Dragon Quest casts are just too limiting, you know? Besides, nobody can relate to wacky characters like a plumber and a plumber's brother, who is also a plumber.
Square Enix has nicely included some characters who will do less to draw players' attention away from the serious business of strategic board game play: "Boy" and "Girl." They look just like we would if we were three feet tall and didn't have noses!
We've got some screens of Boy and Girl, and of Itadaki Street in general, after the break. And check the link for character art and a few board layouts.
