Souls and Zelda probably the closest comparison with the z-targeting, shield blocking, parry and dodging. The amount of weapon types (regular sword, sickle sword, heavy ax, heavy mace, spear, scepter, dual swords and predator bow, light bow, hunting bow, warrior bow) that plays differently actually reminds me of Dark Souls.
Not as slow as Souls, but not as fast as Nier Automata. It's clunky and animation is weird at first, but it grews on me and feels like it's one of the better open world combat especially after you unlock some of the combat moves.
Edit : I played Origins immediately after Unity, they are totally different. I think the only similarities are the parkour, the stealth (feels like the stealth is simpler than Unity though), the sidequests (but this time with accompanying cutscenes, muchhhhh better story/dialogue, and better objective).
