Assassin's Creed Unity is a Current-Gen exclusive game (only available on PS4, Xbox 1 and PC). It follows the story of Arno, during the french Revolution. This game has a HUGE focus on big crowds, open world choices and 4 player Co-Op.
Since you don't have PS4/XBOX1 yet, you won't be able to play this, unless you have a capable PC. Assassin's Creed Rogue on the other hand, is a Last-Gen exclusive game (PS3/ Xbox360 and PC in 2015). You play as Shay, an assassin turned Templar.
It has many of the same mechanics as assassin's creed 4, in which you have a pirate ship and the big open world of the sea. I've heard this was a continuations of AC4, so if you loved that game, get this one. Here are some videos for you to look at!

Ac Unity - is about unity and working in a group of at most 4 players. Ac Rogue kind of counters Unity - in Ac rogue you work alone as an assassin who's gone AWOL. That's sadly all I can give as I don't get too involved into AC's story anymore.
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.
