head to head
Fallout: New Vegas asks more than Squad Assault: Second Wave, and the gap is optimization.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.
Optimization · Pure Optimization
A tactical squad-based shooter set in modern warfare scenarios.
Fallout: New Vegas leans Optimization (Pure Optimization); Squad Assault: Second Wave leans Optimization (Pure Optimization).
Fallout: New Vegas leans a little harder on execution, though the gap is small.
Fallout: New Vegas
Shooter inputs with VATS assist
Squad Assault: Second Wave
tactical shooting inputs, moderate 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
Squad Assault: Second Wave
scripted enemy AI squads, not adaptive
Squad Assault: Second Wave leans a little harder on variance, though the gap is small.
Fallout: New Vegas
Some loot and crit RNG
Squad Assault: Second Wave
random mission events and encounters
Fallout: New Vegas leans clearly harder on optimization.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
Squad Assault: Second Wave
squad tactics and loadout optimization
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.
