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

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

Execution · Practiced Mastery
An action adventure rewarding combat timing against scripted boss patterns.
Crackdown leans Optimization (Practiced Mastery); God of War Ragnarok leans Execution (Practiced Mastery).
God of War Ragnarok leans a little harder on execution, though the gap is small.
Crackdown
Aim, driving, and rooftop leaping
God of War Ragnarok
Parry timing and combo execution in combat
God of War Ragnarok leans a little harder on reads, though the gap is small.
Crackdown
Gangs are static spawn sets
God of War Ragnarok
Bosses use fixed movesets
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Crackdown
Fixed world with placed collectibles
God of War Ragnarok
Negligible randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Crackdown
Skill-orb routing and boss order planning
God of War Ragnarok
Build choices and moveset mastery solve bosses
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.
