Red Dead Redemption (both) are basically cowboy AC but instead of assassins/Templars, it’s just rival gangs in the old west. Even has ‘tracking mode/eagle vision,’ ‘Deadeye/VATS,’ and all that jazz.

The Batman Arkham games are good, though I’ve heard mixed things about Arkham Knight, very stealthy/assassin-y games with Detective/Eagle Vision and sneak takedowns.

If you’re into more exploitation based fantasy rpgs with good combat, Dragons Dogma/Dark Arisen is really good. Pick from warrior/mage/rogue/mix of any 2, and your combat changes based on that and your weapons/magics. Throw smaller enemies like goblins at each other, grab onto a griffin or cyclops to take out its wings or eye. First one is great but heard mixed things about the second, and mtx.
