Nintendo may consider partnering with developers other than DeNA for future mobile games if the demand is there.
Speaking to shareholders during the company's recent financial release, Nintendo President Tatsumi Kimishima said that the company may "ask for additional support from other companies" depending on the state of its mobile business and consumer demand.
However, he also stated that the company is not currently seeking any further partnerships.
"I do not think that we would have been able to provide smart-device applications to our consumers without DeNA's support," he said.
In response to a question on the number of developers currently on its mobile team, Kimishima stated that Nintendo has less than 100 employees working on mobile titles, but did not confirm an exact number.
The board also touched on the development of the Nintendo Switch and its encouragement of third-party support.
Kimishima said that "we have been aiming to realise an environment in which a variety of different third-party developers are able to easily develop compatible software".
Creative Fellow Shigeru Miyamoto backed up these claims, adding that he believes "it would take less than a year for [developers] to port a PC game to Nintendo Switch".
That said, he also praised the company's own staff for working with external engines.
"Nintendoʼs software developers have mastered state-of-the-art technologies such as Unreal engine, and their skills can now be compared with those of Western developers," he said.
