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

Execution · Practiced Mastery
First-person parkour against zombies, especially terrifying after dark.

Execution · Practiced Mastery
Dark-fantasy Doom-engine shooter trading shotguns for elven wands and tomes.
Dying Light 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.
Dying Light
Parkour traversal and melee timing demanding.
Heretic
Classic FPS strafing and aim
Dying Light leans a little harder on reads, though the gap is small.
Dying Light
Zombie AI scripted, non-adaptive.
Heretic
Monsters follow fixed 90s AI
Dying Light leans a little harder on variance, though the gap is small.
Dying Light
Night-hunter encounters bring randomness.
Heretic
Static level layouts
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dying Light
Crafting, blueprints, skill trees solvable.
Heretic
Secret hunting, item hoarding, and route knowledge
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.
