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

Execution · Practiced Mastery
Precision glaive throws against scripted enemies in a cover shooter frame.

Execution · Practiced Mastery
A Himalayan open-world shooter refining the outpost-clearing formula.
Dark Sector leans Execution (Practiced Mastery); Far Cry 4 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.
Dark Sector
Glaive throws with manual curve control reward precise aim
Far Cry 4
Gunplay plus gyrocopter and elephant chaos
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Sector
Infected enemies follow fixed behaviour scripts
Far Cry 4
Scripted outpost AI
Far Cry 4 leans a little harder on variance, though the gap is small.
Dark Sector
Encounters replay identically once learned
Far Cry 4
Wildlife and patrol variation
Far Cry 4 leans a little harder on optimization, though the gap is small.
Dark Sector
Power usage and upgrade choices reward planning
Far Cry 4
Outpost approaches and skill trees are plannable
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.
