The Vita is the more powerful system with better graphics, and more varied games. I would only go with the 3DS if you like the Nintendo game series, like Zelda, Mario, etc. The Vita has a lot of good games coming for, and a lot support it looks like down the road. I personally pick the the Vita because I like the system and the games for it.
But pick whatever one you think you'd like best.
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.
