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.

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

Execution · Practiced Mastery
A Pixar-styled action adventure about a spirit guide cleansing a corrupted forest.
Horizon Forbidden West leans Optimization (Practiced Mastery); Kena: Bridge of Spirits 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.
Kena: Bridge of Spirits
Parry and dodge timing in boss fights
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.
Kena: Bridge of Spirits
Corrupted spirits are fully scripted
Horizon Forbidden West leans a little harder on variance, though the gap is small.
Horizon Forbidden West
Loot rolls and patrol RNG light.
Kena: Bridge of Spirits
World is fixed and explorable
Horizon Forbidden West leans a little harder on optimization, though the gap is small.
Horizon Forbidden West
Deeper gear, weapon techniques, machine weaknesses.
Kena: Bridge of Spirits
Rot ability usage and boss pattern learning
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.
