Ryse: Son of Rome
This isn't Ezio's Rome. Crytek's take on the city's golden period is dark and bloody in this Kinect-based title.
Crytek showed the game off at the Microsoft press conference, and although it wasn't a live demo, it's cool to see someone make a hardcore Kinect game that is built around the peripheral and not just stuffing it into an existing game.
Take a look.
