Miitomo was announced in October and is available on Apple and Android devices, Inquisitr wrote. Although many fans thought that Miitomo is more of a social networking application than a free-to-play mobile game because it allow users to converse with other Nintendo users worldwide.    

However, some fans are worried because free-to-play is seen as unfavorable by the gaming community, cited Tech Radar. Gamers believe that it is the way "to rinse players" of their money if they want to play the game to its fullest making the game not free at all.

Although fans are still in doubt, many are expecting the release of Nintendo games as free mobile games starting next year.
