Me and my friend were talking one day by his driveway and someone put a Walmart bag out on the side of the road for trash and he walked over and in it was a lot of sega genesis games. He wands to put them into his collection except one of them, Street fighter II championship edition. I told him he should keep it for his collection but he wanted to make some money and did not know its worth, we checked online but prices were all over the place so he asked if I knew any people who would know. So would you happen to know how much she would sell for? -thanks, :-)
