Shadow of Mordor is an excellent game that is elevated by the Nemesis System and its many other features working together. It's a great tale in Middle Earth that is faithful to the concepts of Tolkien's world and echoes the tragedy of the likes of Hamlet and Macbeth. I highly recommend this game on new-gen platforms and PC where you can truly appreciate the Nemesis System and open world in all its hi-def epic nature.
The atmosphere in this game is dialled up from the previous, the graphics and design are better and the music has a neat way of tracking the peril you're in. It changes based on the on screen action and provides subtle (or not so subtle) clues to the situation. The same can be said of the sound effects, though they sound mostly recycled from the first game.
