To answer your first question,Yes you can still fight dragons after you defeat alduin,and to your second question,No your not at the end of the game yet even after the fight with Alduin there. Have fun= Edit:Yes even after the main quest dragons are still around to fight,Some are even protecting walls to learn more shouts.
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.
