head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
A dark puzzle-platformer sequel about two children fleeing nightmares.

Execution · Practiced Mastery
Linear sci-fi shooting plus spatial puzzles with fixed solutions.
Little Nightmares II leans Execution (Practiced Mastery); Prey 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 II
More combat and platforming precision.
Prey
Standard FPS aim with portal disorientation added
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Little Nightmares II
Enemies are scripted.
Prey
Alien enemies follow fixed scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Little Nightmares II
Minimal randomness.
Prey
Linear campaign with little randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Little Nightmares II
Set-piece solutions are fixed.
Prey
Portal and gravity puzzles have fixed solutions
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.
