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 Build-engine shooter rewarding fast, precise gunplay and thorough level exploration to find secrets and supplies.
Far Cry leans Execution (Practiced Mastery); Ion Fury leans Execution (Pure Mechanics).
Ion Fury leans a little harder on execution, though the gap is small.
Far Cry
Long-range gunplay against sharp-eyed mercenaries
Ion Fury
Build-engine movement and precise gun skill define the combat ceiling
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
Ion Fury
All enemies are scripted with fixed attack and patrol routines
Ion Fury leans a little harder on variance, though the gap is small.
Far Cry
Patrols vary slightly per attempt
Ion Fury
Level secrets and enemy ambushes are hidden on first run
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
Ion Fury
Ammo conservation and alternate-fire choices reward systematic play
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.
