head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Practiced Mastery
Slow-motion gunfights against aggressive but ultimately mappable squad AI.

Execution · Pure Mechanics
WWII shooter remembered for its Omaha Beach landing and tense rifle duels.
F.E.A.R. 3 leans Execution (Practiced Mastery); Medal of Honor: Allied Assault leans Execution (Pure Mechanics).
Medal of Honor: Allied Assault leans a little harder on execution, though the gap is small.
F.E.A.R. 3
Slow-mo gunplay still rewards fast accurate aim
Medal of Honor: Allied Assault
classic FPS aim, leaning, and sniping
Medal of Honor: Allied Assault leans a little harder on reads, though the gap is small.
F.E.A.R. 3
Squad AI flanks convincingly but follows mappable routines
Medal of Honor: Allied Assault
historic multiplayer scene rewarded outguessing humans
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
Medal of Honor: Allied Assault
scripted ambushes surprise only once
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
Medal of Honor: Allied Assault
encounter memorization, especially Omaha Beach
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.
