Nintendo has a somewhat hesitant relationship with mobile games. The Kyoto company hasn't fully embraced the platform despite the vast commercial opportunities available via the mobile apps ecosystem. But its dipped its toes with the likes of Miitomo and Super Mario Run. But Fire Emblem Heroes marked a more ambitious mobile outing.

The free-to-start strategy and battle game was a clever take on Fire Emblem, retaining enough of the character and idiosyncracies of the beloved series, while shaving down the more complex aspects to suit mobile play. Reviewers thought the graphics were good and the story was slickly presented, but the grinding (and money grubbing) of the game's latter stages were off-putting. It was a simplistic Fire Emblem, all in all. But the latest update for Heroes offers new content to play with.
