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.

Optimization · Systems & Chaos
Sifting a found phone's hidden contents to assemble one fixed mystery.

Optimization · Systems & Chaos
A social-intrigue RPG where you spend skill resources to exploit dinner guests' scripted psychological weaknesses.
Simulacra leans Optimization (Systems & Chaos); The Council leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Simulacra
Tapping through a phone interface
The Council
Menu-driven confrontations; no dexterity.
The Council leans a little harder on reads, though the gap is small.
Simulacra
The entity is scripted horror, not an adapting mind
The Council
NPCs have vulnerabilities and immunities, but fully scripted.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Simulacra
The mystery is hidden information uncovered once
The Council
Hidden character traits and unknown consequences until learned.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Simulacra
Piecing clues from texts and apps is the whole test
The Council
Skill points, effort resources and exploiting known weaknesses are systemic.
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.
