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 · Pure Optimization
Optimising a strict social calendar and fusion economy against scripted dungeon combat.

Optimization · Systems & Chaos
The first Persona, a slow dungeon crawler where random negotiation moods and fusion knowledge rule.
Persona 3 Portable leans Optimization (Pure Optimization); Revelations: Persona 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.
Persona 3 Portable
Menu-driven combat needs no physical skill
Revelations: Persona
Grid-position menu battles; no dexterity.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Persona 3 Portable
Shadows follow scripted weakness patterns, never adapt
Revelations: Persona
Negotiation moods are random scripts, not adaptation.
Revelations: Persona leans a little harder on variance, though the gap is small.
Persona 3 Portable
Tartarus layouts and fusion results carry randomness
Revelations: Persona
Mood rolls and harsh encounter RNG dominate early.
Persona 3 Portable leans a little harder on optimization, though the gap is small.
Persona 3 Portable
Calendar scheduling and persona fusion form a solvable system
Revelations: Persona
Persona fusion and grid positioning are learnable systems.
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.
