So basically the plot of Monster Hunter Now can be summed up like this: "Our world and your world are merging. There are monsters everywhere! Please hunt them before they destroy everything."
Meanwhile, the "monsters" just kind of chill out and don't do much of anything, until you provoke them. You can just walk past them without tapping anything, and everyone's fine.
Doesn't that make the player-character the real villain? I need to think on this.
