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

Variance · Systems & Chaos
Map-and-compass navigation through hidden dangers on a hostile mountain.

Optimization · Systems & Chaos
Sifting a found phone's hidden contents to assemble one fixed mystery.
Kholat leans Variance (Systems & Chaos); Simulacra leans Optimization (Systems & Chaos).
Kholat leans a little harder on execution, though the gap is small.
Kholat
Walking the mountain takes no dexterity
Simulacra
Tapping through a phone interface
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Kholat
The presence stalks on randomised triggers, not a mind
Simulacra
The entity is scripted horror, not an adapting mind
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Kholat
Navigating by map coordinates with hidden danger zones
Simulacra
The mystery is hidden information uncovered once
Simulacra leans a little harder on optimization, though the gap is small.
Kholat
Landmark navigation and route memory converge with repetition
Simulacra
Piecing clues from texts and apps is the whole test
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.
