I vaguely remember reading about how, at the time, one of the most popular apps on the Koryolink smartphones was a strategy rpg video game based on Boy General (DPRK animation that’s super popular with people of all ages). You can also get smartphone games from stores that have things like puzzle games, virtual pets, and even clones of certain western games like angry birds. There’s also a bunch of arcades and entertainment centers in Pyongyang that were funded by Kim Jong Un (along with his funding of things like water parks, amusement parks, skating rinks, etc.) more info here: https://www.youngpioneertours.com/video-games-in-north-korea/
