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 · Systems & Chaos
Surviving and optimising a research facility escape by solving its crafting systems against scripted anomalies.

Optimization · Pure Optimization
Dystopian border-checkpoint sim where stamping passports fast enough feeds your family.
Abiotic Factor leans Optimization (Systems & Chaos); Papers, Please leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Abiotic Factor
Combat in tight facility corridors requires precise aim and positioning
Papers, Please
Document-checking speed directly pays the rent
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Abiotic Factor
Anomaly and creature AI is scripted with fixed patterns
Papers, Please
Entrants are generated, not adaptive opponents
Abiotic Factor leans a little harder on variance, though the gap is small.
Abiotic Factor
Loot crates, anomaly behaviour, and facility section contents carry RNG
Papers, Please
Random entrant documents and scripted-event surprises
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Abiotic Factor
Facility routing, crafting tree unlocks, and power grid design are solvable
Papers, Please
Internalizing rulebooks and inspection workflow efficiency
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.
