Nintendo's Fire Emblem Heroes is the Kyoto-based gaming giant's most successful mobile game to date, earning an estimated $295 million in worldwide player spend during its first year of availability, according to Sensor Tower Store Intelligence data.
As the chart below reveals, mobile gamers spent more than five times as much in Fire Emblem Heroes during its first 12 months than in Super Mario Run, which earned approximately $56 million in gross revenue in the year following its December 15, 2016 launch and sits at about $60 million total. That said, there are obvious and significant differences between the monetization approaches of the two titles that impacted the latter's potential from the outset, namely that Super Mario Run features a one-time paid "unlock" for all its content while Fire Emblem Heroes utilizes more traditional to mobile, random loot mechanisms relying on consumable in-app purchases.

Last month, Fire Emblem Heroes ranked No. 34 for worldwide mobile game revenue on both platforms, while Animal Crossing ranked No. 190, further putting the two titles' degrees of success in contrast.
