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
A psychological horror experience where puzzle knowledge and avoidance routing matter more than combat skill.

Optimization · Practiced Mastery
A linear horror chase game tested by nerve management and environmental navigation under scripted creature pressure.
Silent Hill 2 (2001) leans Optimization (Pure Optimization); Still Wakes the Deep leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Silent Hill 2 (2001)
Clunky combat is intentional; survival over precision
Still Wakes the Deep
Narrow corridor sprints and climbing sections under creature pressure
Silent Hill 2 (2001) leans a little harder on reads, though the gap is small.
Silent Hill 2 (2001)
Monsters follow simple fixed behaviours, never model the player
Still Wakes the Deep
No adaptive opponent; creature follows scripted trigger events
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Silent Hill 2 (2001)
Some item placements are unknown first time; fixed thereafter
Still Wakes the Deep
Creature patrol windows and some object locations are unknown first run
Silent Hill 2 (2001) leans a little harder on optimization, though the gap is small.
Silent Hill 2 (2001)
Puzzle solutions, route knowledge and weapon use are fully learnable
Still Wakes the Deep
Safe-path knowledge and object-use sequences are memorisable
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.
