If you're having trouble tracking down that mystical copy of Sonic Shuffle or Duke Nukem: Total Meltdown (and let's face it, who isn't), the friendly faces at your local GameStop may be able to help. The retailer has expanded (opens in new tab) its business into retro games, and now stocks and sells Genesis, Dreamcast, NES, SNES, N64 and original PlayStation games, consoles and accessories.
The program was previously restricted to test markets, but depending on where you live, you still might not be able to go in and inspect this pre-owned merchandise for yourself, or even purchase what you're looking for at all. Many items are only found in a handful of stores, and roughly half of what GameStop's website lists for each system is not available to order online. Still, expect that to change and stock to replenish, as many an attic and basement are sure to be cleaned out within the coming months.
Now, who wants to play Maximum Carnage on the Genesis with me?
