Games I was pleasantly surprised with were:
Styx
Save 75% on Styx: Master of Shadows on Steam
&
Middle Earth: Shadow of Mordor
Save 75% on Middle-earth?: Shadow of Mordor? on Steam
I'm not even a fan of Lord of the Rings or Hobbit and I really enjoyed Shadow of Mordor, so don't think you have to know or like that world to like the game, I'm sure if you like and know LotR it would make the game even better.
