The game itself features the usual RPG set-up: you start with not so many abilities but the more you progress; you get stronger. At a certain point, rather far in the game, you're allowed to create your own army. This is when Shadow of Mordor took a turn for me and became one of my all-time favourites. Combine this with the Nemesis system which forges mini-storylines between you and your enemies and you have a golden cocktail. I can tell you, this game is a game you'll love. The sequel is even better and more expanded. But this, this is the start. Have fun in Mordor!
