Anybody catch Pawn stars last night. One of the last items to come in the door was a pretty nice collection of Nintendo game and watches. All seemed to work and one was in the box. The seller wanted $400, ended up with $250. I think she was given too little, but it is a pawn shop.
I have only come across one GW in the wild, and that was an oil panic, missing battery door, in a pile of random toys. I have learned to always get dirty and dig into random flea/garage sale boxes. Even picked over sales can turn up gold or oil.
