Monolith's Lord Of The Rings games Middle-Earth: Shadow Of Mordor and Shadow Of War are fun action stealth 'em ups that deserve praise just for their combat. What really makes both worth mention though is the nemesis system that turns procedurally generated baddies into your own personal antagonists the more you encounter them. Why haven't more developers tried their own take on the nemesis system in the last six years? Because Warner Bros. patented it, turns out. That sucks.
