I don’t think there has, I only played a few times but it always seemed like such a rich story and setting for adventures. A world magically ripped apart by the billions of lives extinguished instantly in nuclear fire. Dimensional Beings crossing into the world, from dragons to vampires to leyline walkers.
I only have a few hours a week to play so I like to make the most of my time by playing the fun parts. If a game is single player then cheating let’s me enjoy the little time I have to play it without grinding.
For MGSV if you haven’t cheated yet I suggest it just for the money at least. Download a cheat table and run cheat engine. I don’t like the base building parts of games so I just blew through that by giving myself all the money.
That way I can just do the mission parts of the game without caring what is going on at mother base.
