Rez successor Child of Eden is very good -- check out Ray's review to get the full story on what we thought of it.

It's entirely possible, however, that you haven't picked up a copy of Mizuguchi's musical masterpiece yet. Perhaps you were busy playing something else. Perhaps you wanted to wait until you had a Kinect. Perhaps you wanted the price to drop a bit.

All of these arguments are now invalid. Best Buy is selling the game for $10. According to the retailer's website, the game is currently backordered, meaning that it'll be a week or two before you receive a copy. But for $10 you can't complain too much.

The site doesn't list how long this special price will last for, so if you want a copy, it's probably best to act now.
