i forget...
in the meantime, play an hour of sudoku for free then buy the game for less than 13 bucks.
speaking of sudoku, if you don't own a DS, you should buy one. then you should be absolutely certain that you buy Brain Age (because it is cool and new) and New Super Mario Brothers (for the distilled side-scrolling old-school fun of it). i say this as a gamer not as an employee of Nintendo.
