Kinect has met some healthy scepticism here. Who, we reasoned, wants to actually move? As the bundled software, that's the reluctance that Kinect Adventures has to beat.
To its credit, it works. Ignore its claim of having 20 adventures - these are only minor variations on five themed games, each with their own flavour.
Reflex Ridge is the most active, asking you to jump, squat and perform mini-ballet moves in order to avoid the bumpers, and catch the tokens. It's sweaty work if you're moderately to extremely unfit.
River Rush, meanwhile, transforms from a simple rapids game into a tense platformer, as you shuffle and jump to stay on the bonus tracks. This is Kinect Adventures at its best: the co-op works perfectly to create an atmosphere of friendly recrimination and teamwork.
20,000 Leaks is simple, but another great co-op game, as you plug the holes in your tank with your body. The fraction of a second between movement and Kinect response only becomes a problem in Rally Ball, where the sheer speed works with the unsatisfactory 3D to make you swipe madly at thin air. Accept that it's a game of prediction and luck, rather than quick responses and skill, and it becomes fun - but that's a pretty hefty cognitive leap.
Finally, there's Space Pop - a game that asks you to move in all three dimensions to collide your Avatar with bubbles. Like the other games, it's fun but shallow.
As bundled software it was never designed to be a long-term game, just a fun one - and bearing that in mind, Adventures fills its role perfectly.
Great bursts of short-term, shallow fun
