I'd say its the author trying to fancy up his way off saying he wants clear cut progression to the credits. Say for Gta its just going the mission markers until the credits roll and never taking your car and driving around hitting jumps or splashing pedestrians with fire truck hoses. For Dark Souls the narrative is just running through the mandatory bosses and not taking time to look around and talk to npcs. In MGSV just keep launching those missions and never try to abduct soldiers or build the base or steal equipment.This author is a complete dumbass.
There was literally no focused narrative for Dark Souls, you had to piece the lore together yourself,
MGS5 bounces around from "revenge" to "wolbachia" to "Volgin wants revenge" to "psychic russian can take over robit" to "such a lust for revenge! Whoooooo?" to even more "wolbachia". I'm one of the people who think the story was unfinished.
