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
A first-person shooter campaign set in the future war of the Terminator films.
Horizon Zero Dawn leans Execution (Practiced Mastery); Terminator: Resistance 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.
Terminator: Resistance
Standard FPS gunplay against machines
Horizon Zero Dawn leans a little harder on reads, though the gap is small.
Horizon Zero Dawn
Machines follow fixed patterns, not adapting.
Terminator: Resistance
Terminators run fixed AI routines
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.
Terminator: Resistance
Some unexplored map and loot uncertainty
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.
Terminator: Resistance
Stealth routes, crafting, and skill builds are plannable
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.
