Those of you with Japanese 360s prepare to be all like WTF is this http://www.siliconera.com/2011/10/17/instant-brain-includes-dodonpachi-with-kinect-support/
Yeah, when you play the demo it tells you that this game contains a secret and not to tell your friends. Shit game though. Just like many Japanese graphic novels. Very slow to start and typical story line. Actually, just like Japanese TV Dramas. They're all have the same plot as well. Don't get me wrong, some graphic novel or Adventure games as they're called in Japan are good however this one seems just like a thousand others. Standard art, no fancy effects for page transition and average BGM. Yakumo
I see a crap ton of Demos for them when I log into my Japanese Live account. Being Hiragana illiterate though I don't bother trying them.
The ultimate would be if they put the DDP Campaign Version on but ONLY made it Kinect-playable. IE, controller didn't work. Sadistic.
