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.

Optimization · Practiced Mastery
Expanded machine combat with broader build systems and traversal tools.

Execution · Practiced Mastery
Robot-dinosaur hunting that rewards weak-point study and ranged precision.
Horizon Forbidden West leans Optimization (Practiced Mastery); Horizon Zero Dawn 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 Forbidden West
Faster combat with valor surges and aiming.
Horizon Zero Dawn
Bow aiming and dodge timing matter.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Horizon Forbidden West
Machines remain scripted, not adaptive.
Horizon Zero Dawn
Machines follow fixed patterns, not adapting.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Horizon Forbidden West
Loot rolls and patrol RNG light.
Horizon Zero Dawn
Some loot and patrol randomness.
Horizon Forbidden West leans a little harder on optimization, though the gap is small.
Horizon Forbidden West
Deeper gear, weapon techniques, machine weaknesses.
Horizon Zero Dawn
Weak points, traps, builds fully solvable.
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.
