Sega's Rise of Nightmares does not bode well.
Like the google-eyed face clutched by the creepy claws on the front of the box, it's kinda hard to miss: In fact, it's right there in the marketing taglines for Sega's Rise of Nightmares: "An unashamedly mature title in a sea of family-friendly titles on Kinect."
Let's consider: Mature games for Kinect. Yep, it's a notion that makes about as much sense as Olive Garden deciding to serve tacos and enchiladas alongside its all-you-can-eat shrimp carbonara.

Two-day event includes exclusive reveals, trailers and playable games on show floor.

CEO Haruki Satomi said Sega will "take these lessons into account for future initiatives"

Rovio “found it difficult to advance its initially planned business development,” says Sega.
Wasn't this same thing said about the wii at one time?
Usually M titles produce by mainstream games developers it tend of sell better.
Kinect at this period of time seem to be surrounded by E rated titles an M rated title could be good or bad thing. Good for gamers who been wanting a kinect game with some violence. Bad for parents who thinks the kinect is a safe-haven for child/children friendly games.
Kinect gaming in general is a bad idea...
What people don't realize is that the hardcore STILL don't care and the casuals won't buy them because they most likely brought it for their kids. @ zeal0us if you look at the Wii most M rated titles like House of the Dead, Madworld and Conduit sold worse then Mario and friends.
My answer is no its not always a bad idea.
It is when the games trying to mature Kinect suck.
