I’ve recently been enjoying posts by Motoi Okamoto that take a look at the mobile gaming scene in Japan, offering up analysis on how these games are successful — he’s been sharing them on Gamasutra, but you can follow him directly through his blog as well. His latest post offers up a look at Fire Emblem Heroes. Okamoto spent many years working at Nintendo, and currently runs his own development studio, with a focus on social/mobile games.
