Every February, the Amusement Operator Union holds its annual trade show. Much like the Tokyo Game Show, it's held at Makuhari Messe—right outside of Tokyo—and also much like TGS, it showcases all of Japan's upcoming games—only this time in arcade form.
Other than the incredibly fun Speed of Light, there were several interesting games at AOU 2012. Sega showed off a ring based music game, Maimai, and Konami brought Dance Evolution in arcade form—with Kinect included! Konami also revealed their new mech game Steel Chronicle while Namco-Bandai showcased both Mobile Suit Gundam: Extreme Vs. Full Boost and Tekken Tag Tournament 2.
So now that you know the highlights, check 'em out in action in our video gallery at the top of the page.
