head to head
Resident Evil 7: Biohazard asks more than Amnesia: The Dark Descent, and the gap is optimization.

Optimization · Light / Casual
A first-person horror about exploring a haunted Prussian castle.

Optimization · Practiced Mastery
A first-person haunted-house survival game solved by crafting optimisation and scripted-enemy routing.
Amnesia: The Dark Descent leans Optimization (Light / Casual); Resident Evil 7: Biohazard leans Optimization (Practiced Mastery).
Resident Evil 7: Biohazard leans clearly harder on execution.
Amnesia: The Dark Descent
Stealth and hiding, low demand.
Resident Evil 7: Biohazard
First-person aiming and blocking under Molded pressure matters
Resident Evil 7: Biohazard leans a little harder on reads, though the gap is small.
Amnesia: The Dark Descent
Monsters follow scripted patrols.
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.
Amnesia: The Dark Descent
Minor encounter variation.
Resident Evil 7: Biohazard
Limited item locations are unknown on first visits
Resident Evil 7: Biohazard leans clearly harder on optimization.
Amnesia: The Dark Descent
Oil and sanity management is shallow.
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.
