Sega pretty much controls the surge of Doraemon video games. They also developed Answer X Answer, a popular arcade quiz placed in arcades. For a limited time (i.e. to promote Sega’s latest DS game with the license, Doraemon: Nobita to Midori no Kyojinden DS) the franchises will cross paths. Doraemon questions will pop up in Answer X Answer and in one puzzle players put together fragmented box art for the DS game. Clever branding Sega!
