From DPRK media, KCNA. There's 10 photos of Hwasong on the link.

Kim Jong Un went round a 300-seat video game house built in a characteristic style.

He was pleased to hear that the game house to be furnished with various kinds of facilities is expected to be very popular among young people including children when it is opened. He said that special attention should be paid to the establishment of its operation system and order and the preparations for service as this new space specializing in service for video games is a base of the service field to be opened for the first time in the country.
