So I've never played a Metal Gear Solid game. I know, I know, there goes some gamer credibility. For some reason though, I've never gotten around to it. I've decided to start with Ground Zeroes and The Phantom Pain. I can't get to the other games strictly because I have a big enough backlog. The price point of the games (Whether it's a glorified demo or not) is not an issue to me. I also know basic knowledge of the games but nothing major. Where does GZ take place in comparison to the other games? Will I be hopelessly lost if I start with GZ? And finally, what are just the most essential things to know from the previous games? Thanks in advance!
