I buy and resell lots of games on Ebay, and here is a list of SNES games that I always come across. It seems like whenever I buy a lot of games from someone, the following games are almost always in there:
Batman Forever
any of the Madden Football games.
Frogger
Pac-Man 2: The New Adventures
Wheel of Fortune: Deluxe Edition
Scooby Doo Mystery
Clue
Super Mario World (obviously)
Super Black Bass
Family Feud
I baffles my mind why so many people had these particular games in their collections (other than Mario World of course). What's also interesting is the SNES version of Frogger came out in 1998 when the system was already dead and people had moved on to the Playstation and Nintendo 64...yet the game still ended up in a bunch of people's collections.
