One of the rarest Nintendo games, can now be yours! With just 250.000 of these things being produced, and few surviving to this day, Rain Shower is a bit of a grail among G&W collectors. And hey, the value is bound to rise after that cameo in the Super Mario Galaxy Movie, right? Condition: Good/great. The little knob you have to press, to open the battery lid is a bit worn, but you can still open it without issue.
