Sanma no Meitantei/Detective Sanma (Famicom)

Oh, Japan. You have some of the weirdest, but most innovative, games out there, truly. 
This one is a detective simulator, so we're not sure that counts, but still, it's a very niche genre and they went for it anyways. 
You need to speak Japanese to enjoy this one, but the cover is stillcool as hell, though. 

Please note this is the Japanese version of the game, which requires a Famicom, a converter or a multi-region system to play. 

Condition: Good/great
