Do you know the Kacho? If you’re an average American game fan, probably not, but Gamecenter CX is a popular television show in Japan. Shinya Arino is somewhat of an ambassador for games, retro one specifically, and he will be included in Super Mario Maker as a DLC mystery mushroom skin.
A full translation isn’t available, but you can see Arino play as himself in Super Mario Maker. Arino’s catchphrases are built into the skin, and as a huge fan of GCCX myself, I’m a lil mad that there’s no way we’re ever going to get this in the US. No specific release date has been confirmed.
