When you complete all the quests, you can continue playing in the game world, to unlock achievements, fight, get the secrets and all that. Some of the areas will not be accessible anymore (like the Spire, for instance). About the max amount of gold, I was literally swimming in millions of gold and didn't reach a cap.
Also, gold really means nothing by the time you get to the end of the game, since you can pretty much by everything quite easily. Hope this helps.
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.
