The "Tinkerbell" washing up liquid and "Pluto" chocolate bars that certain bottom-end supermarkets sell would be proof of this point. However, when it comes to Xbox Live Arcade, you can find some real top-notch entertainment for a relatively petite price. There's a lot of dross to wade through, but when you find a gem, it really is a sparkly one."
