head to head
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
Cargo-hauling odyssey where route planning and loadout matter most.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.
Death Stranding 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.
Death Stranding
Balance and traversal inputs, modest demands.
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.
Death Stranding
BTs and MULEs scripted, predictable.
Fallout: New Vegas
Scripted factions and enemies
Death Stranding leans a little harder on variance, though the gap is small.
Death Stranding
Terrain, weather, BT spawns randomized.
Fallout: New Vegas
Some loot and crit RNG
Fallout: New Vegas leans a little harder on optimization, though the gap is small.
Death Stranding
Cargo loadouts, routes, structures highly solvable.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
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.
