Sega uses 'Answer x Answer' arcade game for a little cross-promotion
In March, special Doraemon-themed questions will appear in the quiz game. In addition, a visual puzzle will have players staring at the Doraemon: Nobita to Midori no Kyojinden DS boxart as it is slowly revealed over the course of the game. The game, by the way, is also tied in to the Doraemon movie (warning: sound).
Playing a game and seeing an ad for another game is like using your Little Orphan Annie decoder ring to reveal "Be sure to drink your Ovaltine."
