Wii u, since you already have the wii you can use the remotes and play with all the games you already bought for it + the wii you has amazing exclusive games and lots of new games. The ps4 is the same as the ps3 and the Xbox 360 is also the same as Xbox one. The wii you is like a whole new different console it's not a another version of the wii.
I would recommend getting the PS4 and/or WiiU. I will never recommend getting an Xbox One to anyone.
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.
