The games of Lord of the Rings by Monolith Middle-earth: Shadow Of Mordor and Shadow Of War are fun stealth actions that deserve praise just for their combat. What really makes them both worth mentioning, though, is the nemesis system that turns procedurally generated villains into your own personal antagonists the more you encounter them. Why haven’t more developers tried their own approach to the enemy system in the past six years? Because Warner Bros. patented it. This sucks.
