head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Execution · Practiced Mastery
First-person parkour against zombies, especially terrifying after dark.

Execution · Practiced Mastery
Open-world Stone Age action game about hunting and conquering tribal outposts with tamed beasts.
Dying Light leans Execution (Practiced Mastery); Far Cry Primal leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Dying Light
Parkour traversal and melee timing demanding.
Far Cry Primal
Bow aim, melee timing, beast control under pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dying Light
Zombie AI scripted, non-adaptive.
Far Cry Primal
Scripted tribal AI never models the player
Far Cry Primal leans a little harder on variance, though the gap is small.
Dying Light
Night-hunter encounters bring randomness.
Far Cry Primal
Wildlife encounters and patrol spawns are random
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dying Light
Crafting, blueprints, skill trees solvable.
Far Cry Primal
Outpost routes, crafting economy, beast taming order
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
