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

Optimization · Pure Optimization
Using time-rewind to pre-solve grapple and kill sequences against fully deterministic guard patrols.
Fallout: New Vegas leans Optimization (Pure Optimization); Shadwen 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
Shadwen
Grapple hook timing and kill windows need care but are forgiving
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
Shadwen
Guards follow scripted patrol arcs without profiling player tactics
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas
Some loot and crit RNG
Shadwen
Child NPC pathfinding adds minor unpredictability to routing plans
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
Shadwen
Time-rewind and rope construction enable full pre-optimisation of every kill sequence
