Kinect's pretty much the big topic at the media briefing and Kinect Adventures was just demoed on stage, unveiling some interesting dodging in an MXC style obstacle course and jumping around in a river rafting challenge.
Both mini games that were unveiled under the Kinect Adventures title will have players moving about and jumping to avoid obstacles, stay on course and grabbing tokens for points. It all looks very much like arcade games of old.
Some interesting points include auto split-screen, meaning another player can simply jump in and the screen will automatically split right down the middle. Kinect also automatically takes amusing photos of players while they're playing the game.
All in all, there seems to be a lot of jumping and moving about involved with games under the Kinect title. They seem to be targeted to the mass audience too, not so much the core audience.
