It is normal for parents to name their children "King of Glory". If "Honor of Kings" is not a popular game, regardless of your knowledge of the game, would you feel weird when a parent names their child this name? Won't! Then, there will be no such doubt. Just because we had a preconceived idea and thought he used the game's name, we gave it a different look.
Personal names are inherently very arbitrary. Everyone gives them different meanings, and borrowing hot words is one of them. These parents just borrowed a hot word once, so we don't need to make a fuss. By the time the child's name is called too many times and the game is offline, the name will be more familiar than the game.
