IPad Mini would do the job better as you can use it for different awesome games which are lower in price. Plus you can do many other stuff such and web browsing, watching movies, music, Tv shows, reading books, taking pics and a lot more stuff that it is good at, whereas the Wii U is dedicated to gaming only. I do suggest you read this review on iPad Mini from an actual user, would definitely be helpful on this decision: http://www.amazon.com/review/R1PE94O0M81...
If you want the device solely for gaming, then definitely get the Wii U, you'll have some professional gaming experience. However, if you're just a casual gamer, and you like a portable device so you can game anywhere when you've some time, and have the device for other purposes like web surfing, emails, videos, music, etc., then iPad Mini should do the job well. Games on it are much cheaper as well, though won't be professional games like those on Wii U.

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.
