Nintendo chief executive Satoru Iwata has said the company's strategy in the mobile games market is to "receive a small amount of money from a wide range of consumers."Speaking with investors during a financial results briefing, Iwata said the company would not be able to achieve success in the market by being an imitator."I think many of you here already understand that while it was simple for many to earn revenue in the beginning just from creating a smart device application, the situation has been rapidly changing and now, with intense competition, generating revenue on smart devices is no longer easy," he explained.
