head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Pure Optimization
A refined break-and-boost JRPG won by job and latent-power optimization.

Optimization · Pure Optimization
A calendar JRPG about routing social links and engineering persona fusion chains.
Octopath Traveler II leans Optimization (Pure Optimization); Persona 5 Royal 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.
Octopath Traveler II
Turn-based, no input demand
Persona 5 Royal
Menu-driven combat; no mechanical skill demanded.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Octopath Traveler II
Scripted enemies
Persona 5 Royal
Enemies use scripted weakness AI; not adaptive.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Octopath Traveler II
Hit, crit, and break rolls
Persona 5 Royal
Shuffle time, fusion accidents, and crit rolls.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Octopath Traveler II
Job, latent power, party routing deeply rewarded
Persona 5 Royal
Calendar routing, fusion, and confidant order are deeply solvable.
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.
