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.

Optimization · Practiced Mastery
A demanding action RPG where dodge timing meets alchemy build planning.
Horizon Zero Dawn leans Execution (Practiced Mastery); The Witcher 2: Assassins of Kings leans Optimization (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.
The Witcher 2: Assassins of Kings
Tight dodge and parry windows
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.
The Witcher 2: Assassins of Kings
Scripted enemy patterns
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.
The Witcher 2: Assassins of Kings
Some loot and alchemy variance
The Witcher 2: Assassins of Kings leans a little harder on optimization, though the gap is small.
Horizon Zero Dawn
Weak points, traps, builds fully solvable.
The Witcher 2: Assassins of Kings
Sign, alchemy, and skill builds matter
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.
