I'm afraid the other answer is incorrect. Metal Gear Solid 5 is comprised of two different games: Metal Gear Solid: Ground Zeroes, and Metal Gear Solid V: The Phantom Pain. They are two separate products that encompass the same theme, however they are still considered parts of one game.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
