Penguin-Kun Wars: (Famicom)

Hidden gem alert!
This is a very weird, but very fun, sports-game, that's sort of like table-tennis meets air hockey. It's very easy to pick up and play, and you don't need to know a single word of Japanese. 

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

Condition: Great
