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

Optimization · Pure Optimization
An action-RPG hybrid driven by crafting, specialization, and war-table routing.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.
Dragon Age: Inquisition leans Optimization (Pure Optimization); Fallout: New Vegas leans Optimization (Pure Optimization).
Fallout: New Vegas leans a little harder on execution, though the gap is small.
Dragon Age: Inquisition
Action-leaning combat, dodge timing matters
Fallout: New Vegas
Shooter inputs with VATS assist
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Age: Inquisition
Scripted enemy behaviour
Fallout: New Vegas
Scripted factions and enemies
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Age: Inquisition
Some loot randomization
Fallout: New Vegas
Some loot and crit RNG
Fallout: New Vegas leans a little harder on optimization, though the gap is small.
Dragon Age: Inquisition
Crafting, specialization, war table planning
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
