SEGA sure love to do dancing games, with their release of Space Channel 5 many years back (With Part 2 of the game being released on current-gen consoles in the next month or two) which went as far as having Michael Jackson as one of the heroes who saved the world with his voice….. yeeeeah.
As you can see in this trailer, you will be required to dance to complete the game. Hopefully if this is a major mechanic of the game, that they find a means of increasing the difficulty. In their previous games, Space Channel 5 had you doing more then 10 different button presses in quick succession so hopefully they can do more then one button press at a time.
This game is due out in Early 2012 outside of Japan, with Australia already confirmed to have a release as well. This will be available on the Nintendo 3DS gaming platform.
