'Chop' and 'Mad Riders' rated in Australia

Two mysterious games have appeared on Australia's Ratings Board, one published by Ubisoft for PS3, and one published by Microsoft for an unspecified platform.

The PS3 game in question is called Mad Riders, and carries a G classification, suggesting that nobody is too mad. Microsoft has the Microsoft Studios-made Chop, whose violent title also belies a G rating. Chop was rated concurrently with Grasshopper Manufacture's baseball-action Kinect game Diabolical Pitch and its collaborative shmup Sine Mora, which both earned M ratings.

We've checked in with both Microsoft and Ubisoft, and we'll let you know when we find out what all the chopping and riding is about.
