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
An open-world shooter-RPG won by perk routing and weapon mod optimization.

Optimization · Practiced Mastery
A first-person haunted-house survival game solved by crafting optimisation and scripted-enemy routing.
Fallout 4 leans Optimization (Pure Optimization); Resident Evil 7: Biohazard leans Optimization (Practiced Mastery).
Resident Evil 7: Biohazard leans a little harder on execution, though the gap is small.
Fallout 4
FPS aiming, VATS softens demand
Resident Evil 7: Biohazard
First-person aiming and blocking under Molded pressure matters
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout 4
Scripted enemy AI
Resident Evil 7: Biohazard
Family AI follows scripted stalker scripts, never adapts to you
Resident Evil 7: Biohazard leans a little harder on variance, though the gap is small.
Fallout 4
Loot and legendary rolls
Resident Evil 7: Biohazard
Limited item locations are unknown on first visits
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout 4
Perks, settlement, weapon mod planning
Resident Evil 7: Biohazard
Resource crafting, tape management and route sequencing are fully learnable
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.
