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

Optimization · Pure Optimization
A turn-based JRPG won by persona fusion and social-link routing.

Optimization · Pure Optimization
A narrative RPG that tests knowledge of its philosophical systems and dialogue trees more than any combat skill.
Persona 3 Reload leans Optimization (Pure Optimization); Planescape: Torment 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.
Persona 3 Reload
Turn-based, low input demand
Planescape: Torment
Combat is deemphasised; the game is built to be avoided or trivial
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Persona 3 Reload
Scripted enemies and bosses
Planescape: Torment
NPCs are scripted personalities; no adaptive opponent exists
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Persona 3 Reload
Weakness, crit, and fusion rolls
Planescape: Torment
Some dialogue outcomes and item discoveries are hidden until explored
Persona 3 Reload leans a little harder on optimization, though the gap is small.
Persona 3 Reload
Persona fusion and social link routing central
Planescape: Torment
Stat allocation, dialogue routing and companion management reward system mastery
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.
