If you grew up playing Nintendo games and haven't been able to part with your favorite games, there may be a new reason to give them up.

I don't recall the exact year, but we got a Nintendo game system one year for Christmas and played that thing for days on end! It only came with a few games. Super Mario Brothers, The Legend of Zelda and Duck Hunt are at least a couple that I remember playing until my mom warned we would "burn the game up."

If your games didn't perish after playing them at length, there could be some big money involved!
