head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Optimization · Pure Optimization
Survival horror prequel built on swapping two characters with no item boxes.

Optimization · Systems & Chaos
A combat-free horror reimagining that profiles your psychology and reshapes the story around it.
Resident Evil 0 leans Optimization (Pure Optimization); Silent Hill: Shattered Memories leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Resident Evil 0
Tank-control combat is modestly demanding
Silent Hill: Shattered Memories
Chase sequences need only basic evasion control
Silent Hill: Shattered Memories leans a little harder on reads, though the gap is small.
Resident Evil 0
Enemies follow fixed behaviour
Silent Hill: Shattered Memories
Psych profiling reshapes content but is mappable, not adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Resident Evil 0
Hidden layouts surprise until mapped
Silent Hill: Shattered Memories
Profile-driven changes are hidden first time through
Resident Evil 0 leans a little harder on optimization, though the gap is small.
Resident Evil 0
Two-character item juggling makes routing the real game
Silent Hill: Shattered Memories
Chase routes and profile outcomes converge with knowledge
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.
