Mike Hayes, Boss of Sega US and EU has stated in an interview that, besides Rise of Nightmares, there are more Kinect-exclusive games in the works. In the interview he also states that:
It’s ironic that Sega, probably better known for its family titles, is taking something mature onto it. There’s a lot of Kinect functionality planned for our games going forward – and hopefully a few more exclusives that we’re working with Microsoft on.
He also talks about how other games will have more Kinect supporting features. This only makes sense to me, since Kinect actually sells alright. Can we please have House of the Dead 4 now?
