Nemesis system in AC - which game is ideal?

Having played all the AC games and Shadow of War games, I can't help but feel how incredible Odyssey would be if there was some kind of memorization system(or however it's called) for mercenaries like in shadow of war.

Example you kill a mercenary who's description clearly states 'wife of so and so' and two days later you're casually infiltrating a fort and suddenly you get the mercenary notification and it's the husband coming after you regardless of the bounty

I think this shadow of war nemesis system is patented but just wondered which other AC game would be awesome with such a system?
