It depends on what the game was originally intended for. You could use a virtual computer for example for it, such as XP Mode on Windows 7 Professional, Ultimate and Enterprise, or you could use VirtualBox, which is free of charge for example. Another option is DOSBox, but this is only a solution is the game was originally intended for DOS.
I use DOSBox for running about 8GB of old DOS games. ;).
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.
