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
Methodical infiltration planning paid off by one well-compensated rifle shot.
Dying Light leans Execution (Practiced Mastery); Sniper Elite: Resistance 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.
Sniper Elite: Resistance
Ballistics-compensated shots and stealth timing need steady hands
Sniper Elite: Resistance leans a little harder on reads, though the gap is small.
Dying Light
Zombie AI scripted, non-adaptive.
Sniper Elite: Resistance
Invasion mode adds occasional human cat-and-mouse
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dying Light
Night-hunter encounters bring randomness.
Sniper Elite: Resistance
Patrol details are scripted-but-unknown on first infiltration
Sniper Elite: Resistance leans a little harder on optimization, though the gap is small.
Dying Light
Crafting, blueprints, skill trees solvable.
Sniper Elite: Resistance
Route planning, sound masking and shot setups reward study
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.
