I've played all the titles except for Peace Walker, the story of which plays a big part in Ground Zeroes and Phantom Pain apparently. There is a very vast story and history but even having played most of them I still don't know wtf is going on most of the time. It's all quite over the top and convoluted in my opinion. The gameplay is what makes this series, and what I have followed of the story is pretty good, but I'd go as far as to say the games can be enjoyed as standalone titles for their gameplay alone. There is very little story in Ground Zeroes though, so that should at least be able to tell you whether you'll enjoy Phantom Pain, which is looking pretty amazing. Can always watch a YouTube video to catch up on the story too, which is what I plan to do before the release in September as I'm sure I've forgotten most of it except for a few significant characters.
