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

Optimization · Practiced Mastery
A Revolution-era Paris entry built around dense crowds and open-ended blackbox assassinations.

Execution · Practiced Mastery
A deliberately paced shooter testing easy aim and light build choices in scripted missions.
Assassin's Creed Unity leans Optimization (Practiced Mastery); RoboCop: Rogue City 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.
Assassin's Creed Unity
Refined parkour, still forgiving combat
RoboCop: Rogue City
Deliberate aiming with a tanky hero, light demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed Unity
Co-op partners face scripted guards
RoboCop: Rogue City
Criminal AI runs simple fixed scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed Unity
Fixed sandbox assassinations
RoboCop: Rogue City
Linear missions hold little hidden or random
Assassin's Creed Unity leans a little harder on optimization, though the gap is small.
Assassin's Creed Unity
Gear builds and blackbox approach planning
RoboCop: Rogue City
Skill points and pistol upgrades structure modest build planning
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.
