It's a game plot that's so perfect that it might as well be the only game plot. It gives itself so little wiggle room to fail. There are very few twists, unless you count the fact that when you beat a monster in the head for long enough, it will go from "slightly furious" to "intensely furious." Like Teddy Roosevelt, you use the body parts of those monsters to craft better weapons and armor pieces. When you play online multiplayer, you can tell who plays it casually and who is dedicated by what they wear. The dedicated are suited in a matching set of monster scales. The casual, like me, are dressed in a random array of fins and hides, serving only to tell the non-playable characters, "I have murdered most of your ecosystem, and I did it myyyyyyy waaaaaayyyyy." And then there are your warrior pets.
In Monster Hunter 4 Ultimate and Monster Hunter Generations, my right-hand man is a really industrious cat. Called "Palicoes" in the game, these guys follow you around, find items, and help out in battles with animals 200 times their size. These cats aren't scared of anything. Their only response to facing down a 12-ton mega spider is a hearty "Charge!" as they barrel into the fray. Aside from that, they "MROW" constantly, as do all the wild Palicoes that you encounter. I know it sounds like a weird addition, but there's something comforting about having a cat purring around when you decimate any example of wildlife that's taller than you.
Just look at him. I'm gonna name him BLOODLUST.
