Skyrim and StarCraft II are probably the biggest ones that come to mind as well as World of Warcraft. Crysis is CPU and GPU intensive. In general, stuff that has a lot going on at once, like real time strategy games and MMORPGs, tend to be more CPU intensive because you have to be able to process, say, a few hundred units on screen at once or a full 25-man raid all shooting off spells, that sort of thing.
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.
