head to head
Path of Exile 2 asks more than Fallout: New Vegas, and the gap is variance.

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

Optimization · Pure Optimization
A demanding action RPG where deliberate execution and deep build optimisation meet layered crafting variance.
Fallout: New Vegas leans Optimization (Pure Optimization); Path of Exile 2 leans Optimization (Pure Optimization).
Path of Exile 2 leans clearly harder on execution.
Fallout: New Vegas
Shooter inputs with VATS assist
Path of Exile 2
Slower, more deliberate combat raises the mechanical precision 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
Path of Exile 2
PvE only; bosses are scripted, not adaptive
Path of Exile 2 leans clearly harder on variance.
Fallout: New Vegas
Some loot and crit RNG
Path of Exile 2
Drop systems and crafting RNG remain central to the experience
Path of Exile 2 leans a little harder on optimization, though the gap is small.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
Path of Exile 2
Build theory and passive tree navigation reward deep system knowledge
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.
