That Nemesis System was a stroke of inspired cleverness by developer Monolith Games, an idea that players wanted to see copied and pasted in other games. To a certain extent, Ubisoft’s upcoming Assassin’s Creed Odyssey will have its own take on the gameplay mechanic, offering players Mercenaries instead of Nemesises…Nemesi…dammit what’s the plural of Nemesis I should know this oh right it’s Nemeses.
