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
A Himalayan open-world shooter refining the outpost-clearing formula.

Execution · Practiced Mastery
Dark-fantasy Doom-engine shooter trading shotguns for elven wands and tomes.
Far Cry 4 leans Execution (Practiced Mastery); Heretic 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.
Far Cry 4
Gunplay plus gyrocopter and elephant chaos
Heretic
Classic FPS strafing and aim
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Far Cry 4
Scripted outpost AI
Heretic
Monsters follow fixed 90s AI
Far Cry 4 leans a little harder on variance, though the gap is small.
Far Cry 4
Wildlife and patrol variation
Heretic
Static level layouts
Far Cry 4 leans a little harder on optimization, though the gap is small.
Far Cry 4
Outpost approaches and skill trees are plannable
Heretic
Secret hunting, item hoarding, and route knowledge
