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

Optimization · Practiced Mastery
Open-world superagent sandbox about leveling skills and hunting 500 agility orbs.

Optimization · Practiced Mastery
An action RPG where leveling means choosing which Londoners to drain.
Crackdown leans Optimization (Practiced Mastery); Vampyr leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Crackdown
Aim, driving, and rooftop leaping
Vampyr
Dodge-and-stamina melee combat with modest demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Crackdown
Gangs are static spawn sets
Vampyr
Enemies follow scripted patterns
Vampyr leans a little harder on variance, though the gap is small.
Crackdown
Fixed world with placed collectibles
Vampyr
Citizen secrets are hidden until investigated
Vampyr leans a little harder on optimization, though the gap is small.
Crackdown
Skill-orb routing and boss order planning
Vampyr
The feed-or-spare XP economy is the central solvable system
