Nintendo doesn't need any of Rare's shit.
>Splatoon is a shooter that is bigger than Perfect Dark, Jet Force Gemini and Goldeneye combined.
>Mario Kart is infinitely bigger than Diddy Kong Racing.
>Mario is infinitely bigger than Banjo.
I'm 100% sure if you ask anyone at Nintendo in Japan who Rare is, they will say, "Who the fuck is that"?
