How important was Mr. Mori's advice in preventing the made-up portion from becoming too unrealistic?

There are not many aspect of the game that are too unrealistic. I think Mr. Mori though about it, but he also has a taste for the entertainment industry, so he didn't think of the game as being too realistic. For example, when Snake enters a room with his gun, the barrel is pointing at the ceiling, which is in fact technically incorrect.

Are all tanks and stealth helicopter based on real-life counterparts? Regarding the modeling of the tanks, we actually went to see them and also we made various kinds of plastic models. Weapon wise, two-thirds are real, and one-third unreal.

For example, the remote-control missile: Although in real life a larger version exists, there in so version as small as this one. Did you include the fictional weapons because you wanted to do something exciting in the game, or because you needed that weapon's capability for the scenario? Yes, I made those to increase the enjoyment, because this time the game environment is in 3D.

I tried to make the game world ... more.

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.
