Kouhei Maeda, one of the team who has worked on Fire Emblem Heroes recently took part in an interview with IGN. Maeda explained to the publication that the ground work for Fire Emblem Heroes and what the team have learnt from feedback will really help when they approach other mobile titles.
“What we’ve learned from working on Fire Emblem Heroes will really help us as we work on future games. As we’re working on future games, we’re thinking about what is it that fans want and what is it fans like, and we’re able to look at the data we get from Fire Emblem Heroes [and apply that].”
