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 prequel third-person shooter emphasizing scripted encounters and loadout choices.

Execution · Practiced Mastery
An action RPG where narrative depth is paired with moderately solvable combat systems.
Lost Planet 3 leans Execution (Practiced Mastery); NieR 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.
Lost Planet 3
third-person shooting and mech-suit control
NieR
combat timing and dodges matter
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Lost Planet 3
enemies use fixed scripted AI patterns
NieR
scripted enemies, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Lost Planet 3
minor spawn and damage randomness
NieR
loot and encounter randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Lost Planet 3
loadout and mission-route optimization
NieR
builds and side systems 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.
