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

Execution · Practiced Mastery
Robot-dinosaur hunting that rewards weak-point study and ranged precision.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.
Horizon Zero Dawn leans Execution (Practiced Mastery); Red Dead Redemption 2 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.
Horizon Zero Dawn
Bow aiming and dodge timing matter.
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Horizon Zero Dawn
Machines follow fixed patterns, not adapting.
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Horizon Zero Dawn
Some loot and patrol randomness.
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Horizon Zero Dawn leans a little harder on optimization, though the gap is small.
Horizon Zero Dawn
Weak points, traps, builds fully solvable.
Red Dead Redemption 2
Loadouts and routes solvable but loose.
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.
