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

Variance · Systems & Chaos
Learning a stalker's rules and safe routes across time-hopping nights.

Optimization · Systems & Chaos
An open-town horror entry with dynamic rain that intensifies the otherworld.
Five Nights at Freddy's: Into the Pit leans Variance (Systems & Chaos); Silent Hill: Downpour 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.
Five Nights at Freddy's: Into the Pit
Hiding and fleeing need timing but stay forgiving
Silent Hill: Downpour
Improvised melee asks little mechanical skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Five Nights at Freddy's: Into the Pit
The animatronic stalks via game rules, not a mind
Silent Hill: Downpour
Enemies and the Void are scripted
Five Nights at Freddy's: Into the Pit leans a little harder on variance, though the gap is small.
Five Nights at Freddy's: Into the Pit
Pursuer behaviour and clue locations are hidden until learned
Silent Hill: Downpour
Weather shifts and side quests hide information first run
Silent Hill: Downpour leans a little harder on optimization, though the gap is small.
Five Nights at Freddy's: Into the Pit
Mapping safe routes and puzzle steps converges quickly
Silent Hill: Downpour
Routes, puzzles, and morality endings are solvable
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.
