Hey, you. Yeah, you reading this right now. Do you want River City Ransom EX sealed for $17? If you're ready to say anything but "yes," we kindly ask that you close your browser window, call your mother and apologize for being such a disappointment.
If for some reason you're not keen on the game and still manage to have a working brain (or, you know, you already own it), there's plenty of other Game Boy and Game Boy Advance games on offer. It's a nice mixture of great first-party and third-party titles, if we may say so. You know, in case you wanted to bulk up your GBA collection.
