head to head
Fallout: New Vegas asks more than Persona 3 Reload, and the gap is execution.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.

Optimization · Pure Optimization
A turn-based JRPG won by persona fusion and social-link routing.
Fallout: New Vegas leans Optimization (Pure Optimization); Persona 3 Reload leans Optimization (Pure Optimization).
Fallout: New Vegas leans clearly harder on execution.
Fallout: New Vegas
Shooter inputs with VATS assist
Persona 3 Reload
Turn-based, low input demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas
Scripted factions and enemies
Persona 3 Reload
Scripted enemies and bosses
Persona 3 Reload leans a little harder on variance, though the gap is small.
Fallout: New Vegas
Some loot and crit RNG
Persona 3 Reload
Weakness, crit, and fusion rolls
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
Persona 3 Reload
Persona fusion and social link routing central
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.
