Pre-owned Madden football games are everywhere. When you have a series that has been churning out a title every year for twenty years, there are a lot of discarded games to be peddled. The picked-through seller at the flea market is guaranteed to have a stack of PS2 Madden titles to sift through. Your neighbor’s garage sale is going to have recent versions for next-to-nothing prices since everyone only wants to play the most recent iteration.
Sports games were never really my thing (excepting hockey games, that is!), so finding out that John Madden Football had a rare Genesis variant was quite a surprise!
