Metal Gear: Best to Worst
I played through all of the Metal Gear games in chronological order (Snake Eater -> Guns of the Patriots) over the past few years and ranked them as I went. There was a period where I had to take my time because the next game, The Phantom Pain, wasn't out yet, but after that I was able to get through them pretty quickly. I started Rising, but I don't know if I'll finish it. I'll update this list if I do. Let me know if it's really vital, but I think I got enough from these ones.
