I haven't played any other MGS game before this one (because they're not on pc, otherwise I would have) but after playing Ground Zeroes and reading some of the backstory/lore, I felt like i knew enough going into this game.
The story is just huge, with lots of characters and a lot of events that happened in previous games, but it never felt overwhelming. The gameplay is pretty good, though later in the game there are some really weird "pay2win" aspects. Not necessarily wherw you have to pay to gain better gear, but building and developing new items takes real time and you can pay a different currency from the main in-game currency to make these things develop/build faster. But overall it's a pretty good game.
