The NES classic Double Dragon 2 unexpectedly shows up on Wii today, in an otherwise portable-heavy week. Today's 3DS releases include the popular Order Up!!, and a series of "Slitherlink" math puzzles.

Normally, we don't give too much attention to the kids' stuff on DSiWare, but we feel compelled to share this. There is a game called Lola's Fruit Shop Sudoku, and it is a sudoku game designed for four-year-olds. You line up pictures of fruit instead of numbers. This is incredible.
