DREAM C CLUB（ドリームクラブ）
Found a cute (and sexy) promotional video for Dream C Club while browsing Nico.
As far as I can tell, it's an XBox 360 release. It appears to be a rhythm game with some visual novel/date-sim elements, and extremely cute girls.
It could very well be an H-game, but considering that it's a console release, they probably kept to to suggestive.
The graphics look really nice. Developers are taking full advantage of the 360's rendering capabilities. If only more games looked like that (the rendering style, though I wouldn't mind more cute girls in games either).
All of the girls' boobs appear to have their own physics engine applied or something, their hair doesn't even move as smoothly.
Below is the nico link to the video. Enjoy ;)
