A few days ago, I had snagged this wonderful gem:

Streets of Rage 2, a Sega Genesis classic, for $5. Initially I passed on this, but then I realized it’s Streets of Rage 2, a freakin’ Genesis classic. That Yuzo Koshiro soundtrack! Who could pass that up? The dummy writing this. Thankfully, I was able to correct my mistake and grab it as a wonderful addition to my Genesis collection, along with a Sonic cartridge compilation called Sonic Classics.
Granted, it’s just a cartridge copy and it isn’t in the best of shape, but it’s nice to have. There’s something special about this cartridge: The giant “NOT FOR RESALE” label on it. Anyone who’s into collecting Sega Genesis stuff may have also seen the big “NOT FOR RESALE” stickers on copies of Sonic the Hedgehog. My Sonic the Hedgehog 2 came with my Sega Genesis long ago also with a “Not for Resale” sticker on it. Many pack-in games on the Genesis also came with the “not for resale” sticker on them. It made me wonder: Why is this ugly text on there, and what was its purpose?
At first, I thought this meant so that these couldn’t be resold at second-hand shops, but that wouldn’t make any sense, even when this was new. After doing a bit of research and asking a friend, it turns out it’s a much more sinister story.
