Player spending hit a new record of $117 million during the fourth quarter of 2018, a 47 percent increase over the fourth quarter of 2017. Overall, Nintendo increased its earnings 15 percent compared to 2017.
Much of the money that Nintendo earned came from Fire Emblem Heroes, its most popular title. Fire Emblem Heroes accounted for approximately 66 percent of Nintendo's 2018 revenue, with more than $230 million spent in the game across the globe.
Since its debut, Fire Emblem Heroes has earned more than $487 million.
Though it is Nintendo's newest game, Dragalia Lost brought in an estimated $58.4 million worldwide, while Animal Crossing: Pocket Camp, which turned a year old in November, earned Nintendo $48.6 million during 2018.
Nintendo's original mobile game and first paid title, Super Mario Run, brought in just $10 million in 2018, down from $31 million in 2017.
In 2019, Nintendo plans to expand its portfolio of mobile titles with the launch of Mario Kart Tour, set to be released in March. Like Fire Emblem Heroes, Dragalia Lost, and Animal Crossing: Pocket Camp, Mario Kart Tour will be free to play and supported through in-app purchases.
