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 about a tiny girl in a grotesque world.

Execution · Practiced Mastery
Thirties crime drama of authored missions and unforgiving period driving.
Little Nightmares leans Execution (Practiced Mastery); Mafia 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.
Mafia
Punishing shootouts and the infamous race
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Little Nightmares
Enemies are scripted.
Mafia
Cops and gangsters follow scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Little Nightmares
Minimal randomness.
Mafia
Missions are fully authored
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.
Mafia
Learning mission layouts and car handling
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.
