Fire Emblem Heroes [Free] has already proven to be a smash hit for Nintendo, at one point topping even Clash of Clans and Game of War in the App Store's Top Grossing charts. That said, the combination of a well-known brand and Nintendo's name almost ensures that any release from the company will make a mark in the charts. What Nintendo has yet to pull off is keeping an app there. Though Fire Emblem has slid a little bit, it's still doing quite well. In hopes of keeping that fire burning, Nintendo has sent out a notice detailing a few changes coming to the game in the next few weeks.
As mentioned, Fire Emblem Heroes has already started to cool off. There could be many reasons for that. Many players have long since plowed through the majority of the story missions, leaving little to do. The Arena mode has some serious balancing issues to work out, too. In general, the game doesn't seem to scale well at the higher end. Stamina never increases even as the cost of attempting stages goes up, there's no way to increase the size of your friend list, and ranking characters up requires an almost comical amount of an item that is relatively hard to come by. Not all of these points are addressed by the coming changes, but what's here should alleviate some burdens.
