I have family and friends who are gamers and I never heard of it
It is a Japanese MMORPG popular among hacker and really deep in gamers because of the complexity of the setup and play. Imagine Warcraft crossed with Halo but with Pentagon super computer power behind it.

I just looked at some YouTube videos of the Dynasty Warrior series, It looks like a sword and sorcery type of game and not the tactical warfare genre that uses firearms. I don’t get the connection between this game and the shooting of children. Anybody have a different take?
