My generation has fond memories of racing to the television in the afternoons and on Saturday mornings to watch cartoons such as Captain N: The Game Master, The Super Mario Bros. Super Show (and it's spin-offs The Adventures of Super Mario Bros. 3 and Super Mario World), The Adventures of Sonic the Hedgehog (and it's counterparts Sonic the Hedgehog and Sonic Underground), and other gaming cartoons, and over the past few years, Shout! Factory has worked hard to bring them all (and a few others) to DVD. Unfortunately, at the end of the year those license agreements expire, so the entire catalog is about to go out of print. If you've been dragging your feet on picking up any of these box sets, you really need to get moving. Shout!'s online store is liquidating inventory until the end of July and Amazon.com is offering up bigger bargains, so it's worth pursuing if you need stubby green Mega Man in your life or want to show your kids that one episode in which Sonic saves Christmas.
