Nintendo announces its first smartphone game, but is it too little too late?

During a meeting with investors earlier this week, Nintendo unveiled its very first smartphone game. Dubbed "Miitomo," this free-to-play game lets you use an adorable avatar to interact with your friends without investing in Nintendo hardware. This certainly isn't the kind of mobile game many of us were hoping for, but can this oddball social game keep this gaming giant relevant in a rapidly evolving market?
