head to head
Final Fantasy XIV asks more than Fallout: New Vegas, and the gap is execution.

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

Optimization · Pure Optimization
An MMORPG where scripted raids reward rotation execution and route memorization.
Fallout: New Vegas leans Optimization (Pure Optimization); Final Fantasy XIV leans Optimization (Pure Optimization).
Final Fantasy XIV leans clearly harder on execution.
Fallout: New Vegas
Shooter inputs with VATS assist
Final Fantasy XIV
Tight raid rotations and mechanic dodges
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
Final Fantasy XIV
Bosses follow fixed scripted timelines
Fallout: New Vegas leans a little harder on variance, though the gap is small.
Fallout: New Vegas
Some loot and crit RNG
Final Fantasy XIV
Very little RNG in core content
Final Fantasy XIV leans a little harder on optimization, though the gap is small.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
Final Fantasy XIV
Rotations and raid solves are theorycraft puzzles
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.
