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

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

Execution · Practiced Mastery
Claustrophobic post-apocalyptic shooter where bullets double as currency.
Horizon Zero Dawn leans Execution (Practiced Mastery); Metro 2033 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.
Metro 2033
scarce-ammo gunfights punish sloppy aim
Horizon Zero Dawn leans a little harder on reads, though the gap is small.
Horizon Zero Dawn
Machines follow fixed patterns, not adapting.
Metro 2033
mutants and bandits follow scripts
Metro 2033 leans a little harder on variance, though the gap is small.
Horizon Zero Dawn
Some loot and patrol randomness.
Metro 2033
hidden moral points and supplies first run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Horizon Zero Dawn
Weak points, traps, builds fully solvable.
Metro 2033
ammo-as-currency economy and stealth routing
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.
