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
The original open-ended tropical shooter testing long-range aim and approach planning.

Execution · Pure Mechanics
A fast-paced shoot-em-up testing aim and reload management against enemy waves.
Far Cry leans Execution (Practiced Mastery); Let Them Come leans Execution (Pure Mechanics).
Let Them Come leans a little harder on execution, though the gap is small.
Far Cry
Long-range gunplay against sharp-eyed mercenaries
Let Them Come
Twitch aiming and reload timing dominate survival
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Far Cry
AI flanks but follows mappable behaviour
Let Them Come
Enemy waves are scripted, not adaptive
Let Them Come leans a little harder on variance, though the gap is small.
Far Cry
Patrols vary slightly per attempt
Let Them Come
Wave composition and spawns vary somewhat
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Far Cry
Approach planning across open tropical maps
Let Them Come
Weapon upgrades and resource choices extend runs
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.
