head to head
Neither is simply harder - they are hard in different places. Fallout: New Vegas demands more execution; Pathfinder: Wrath of the Righteous demands more variance.

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

Optimization · Pure Optimization
A mythic-power fantasy where stacking mythic abilities and prestige chains produce near-godlike optimization results.
Fallout: New Vegas leans Optimization (Pure Optimization); Pathfinder: Wrath of the Righteous leans Optimization (Pure Optimization).
Fallout: New Vegas leans clearly harder on execution.
Fallout: New Vegas
Shooter inputs with VATS assist
Pathfinder: Wrath of the Righteous
Real-time-with-pause eliminates any twitch skill requirement
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
Pathfinder: Wrath of the Righteous
All enemies follow scripted AI; crusade campaign is deterministic
Pathfinder: Wrath of the Righteous leans clearly harder on variance.
Fallout: New Vegas
Some loot and crit RNG
Pathfinder: Wrath of the Righteous
Mythic ability unlock order and hidden enemy resistances add unknown layers
Pathfinder: Wrath of the Righteous leans clearly harder on optimization.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
Pathfinder: Wrath of the Righteous
Mythic path stacking and Lich-specific build chains reach absurd optimization ceilings
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.
