Eiji Aonuma has stated that Nintendo will continue to look to external development teams to aid them on projects that will necessitate “massive resources”.
Within the past year, Grezzo aided development of The Legend of Zelda: Ocarina of Time 3D, Retro Studios assisted with Mario Kart 7 tracks, and Monolith Software helped with graphical work on The Legend of Zelda: Skyward Sword.
Such assistance has worked for Nintendo, and will be something the company will continue to pursue.
“Nintendo’s developers will continue to work on a number of different titles, and I think that we will have to rely on outside companies for graphics and other elements that require massive resources,” Aonuma explained.
“I’m satisfied when the cooperation between Nintendo and other companies becomes something meaningful for both parties.”
