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

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

Execution · Practiced Mastery
Open-world western about an outlaw forced to hunt down his old gang.
Dying Light leans Execution (Practiced Mastery); Red Dead Redemption leans Execution (Practiced Mastery).
Dying Light leans a little harder on execution, though the gap is small.
Dying Light
Parkour traversal and melee timing demanding.
Red Dead Redemption
Dead Eye softens but gunplay still wants aim
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.
Red Dead Redemption
Multiplayer skirmishes add light human prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dying Light
Night-hunter encounters bring randomness.
Red Dead Redemption
Ambient events and spawns vary mildly
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.
Red Dead Redemption
Mission approaches and economy are learnable
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.
