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.

Variance · Systems & Chaos
PS2 survival horror about evading relentless stalkers with help from a loyal dog.

Optimization · Systems & Chaos
Stealth puzzle horror about breaking into a suburban neighbor's secret-filled house.
Haunting Ground leans Variance (Systems & Chaos); Hello Neighbor 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.
Haunting Ground
Panic-state control and evasion timing
Hello Neighbor
Light sneaking and parkour
Hello Neighbor leans a little harder on reads, though the gap is small.
Haunting Ground
Stalkers react but follow mappable logic
Hello Neighbor
Marketed adaptive AI is mostly mappable in practice
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Haunting Ground
Stalker patrols and panic system feel unpredictable
Hello Neighbor
Neighbor patrols and traps feel erratic
Hello Neighbor leans a little harder on optimization, though the gap is small.
Haunting Ground
Hiding spots, Hewie commands, and puzzle routes converge
Hello Neighbor
Puzzle solutions and route knowledge solve each act
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.
