I was in Gamestop today picking up a battered copy of Princess Tomato for the NES (it looks like it was submerged underwater for a long period of time and then buried in someone's backyard, but it works fine surprisingly) and saw a very strange Genesis cart. It had a light green label with something like N0176 on the top of the label (those aren't the exact numbers, it just looked something like that). I pulled it out of the rack and it says "Game Factory" at the bottom and in the middle of the label there is a black box with the words "Place Label Here". Someone wrote "Sonic the Hedgehog 3" in black marker in the box instead of placing a label there. What exactly is this game? I thought I may have stumbled onto something with potential value, but since I've never heard of these "Game Factory" games and don't have any idea what it is, I figured it was too risky to spend $7 on. It's being sold as a Sonic 3 cart. Is it worthless, or is it some kind of oddity that's worth some money?
