Nintendo executives have dropped an unsubtle hint that it is working on a peripheral to enable people to play its action games on smartphones. At the firm's annual shareholders meeting, Shinya Takahashi said that his team have looked at third-party controllers on the market and "may develop something new by ourselves." Takahashi was responding to the question that playing Nintendo's more famous titles (i.e. Mario) is difficult using the virtual controls that are available with touchscreen devices. After all, it's clear that more than a few people would be happy to lay down money to play a classic Mario title on their smartphone.
