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
Slow-motion gunfights against aggressive but ultimately mappable squad AI.

Execution · Practiced Mastery
Frozen-planet shooter about managing heat while gunning down giant bugs.
F.E.A.R. 3 leans Execution (Practiced Mastery); Lost Planet: Extreme Condition 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.
F.E.A.R. 3
Slow-mo gunplay still rewards fast accurate aim
Lost Planet: Extreme Condition
Grapple movement and Akrid weak-point shooting
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
F.E.A.R. 3
Squad AI flanks convincingly but follows mappable routines
Lost Planet: Extreme Condition
Multiplayer modes add some mind games
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
F.E.A.R. 3
Encounter layouts are scripted-but-unknown first time
Lost Planet: Extreme Condition
Campaign encounters are fixed
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
F.E.A.R. 3
Cover usage and power timing are quickly learned
Lost Planet: Extreme Condition
Thermal energy management and boss weak points
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.
