This morning, Nintendo and mobile gaming company DeNA announced a business and capital alliance to bring Nintendo IP to mobile devices. In this arrangement, both Nintendo and DeNA will develop and maintain game apps featuring characters pulled from Nintendo's formidable roster of recognizable properties. These apps will be playable on smart phones and tablets.
Fans hoping to see Super Mario World (legitimately) ported to their mobile devices are in for some disappointment, though. All games developed as mobile apps will be completely original and created specifically for mobile. This also means that there will be no cross releases between 3DS and mobile, or vice versa.
Interestingly, Nintendo seems to have left all of its IP on the table as being eligible for app development. Usually Nintendo is very guarded with its IP, so this open approach comes as a bit of a surprise.
In addition to game development, DeNA will be helping Nintendo to develop an new online membership service. This new service will be accessible from mobile devices, PC, and Nintendo systems. Nintendo will be relying heavily on DeNA's expertise for this new online membership system. The service is set for launch this coming fall.
