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.

A dark puzzle-platformer about a tiny girl in a grotesque world.

Execution · Practiced Mastery
A 2.5D platformer with deep user-created content.
Little Nightmares leans Execution (Practiced Mastery); LittleBigPlanet 3 leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Little Nightmares
Stealth platforming demands timing.
LittleBigPlanet 3
Floaty platforming with varied character moves
LittleBigPlanet 3 leans a little harder on reads, though the gap is small.
Little Nightmares
Enemies are scripted.
LittleBigPlanet 3
Scripted enemies
LittleBigPlanet 3 leans a little harder on variance, though the gap is small.
Little Nightmares
Minimal randomness.
LittleBigPlanet 3
User levels vary wildly
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Little Nightmares
Routes have fixed solutions.
LittleBigPlanet 3
Costume and prize-bubble routing
