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

Execution · Practiced Mastery
A retro-Soviet action shooter mixing gunplay with light upgrade strategy.

Execution · Practiced Mastery
Robot-dinosaur hunting that rewards weak-point study and ranged precision.
Atomic Heart leans Execution (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.
Atomic Heart
Shooting and dodging carry the combat.
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.
Atomic Heart
Robot enemies follow scripted patterns.
Horizon Zero Dawn
Machines follow fixed patterns, not adapting.
Horizon Zero Dawn leans a little harder on variance, though the gap is small.
Atomic Heart
Encounters largely fixed.
Horizon Zero Dawn
Some loot and patrol randomness.
Horizon Zero Dawn leans a little harder on optimization, though the gap is small.
Atomic Heart
Upgrades and weapon crafting learnable.
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.
