Apparently Square Enix did decent business on the first series of World Walking travel guide things, or at least made back their teensy budget. Maybe the team knows a guy who travels a lot and has a poor sense of direction. Whatever the reason, they're expanding the line, with another set of DS cards with maps and helpful cultural information.
The World Walking non-games provide travelers with maps with landmarks and touristy points of interest marked. They also include pictures of attractions, information about local culture and food, and even niceties like dual time zone clocks. Oh, and also minigames, but you surely knew that.
