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.

Optimization · Practiced Mastery
Routing scripted patrols with vampire teleports and a light skill-build layer.
Assassin's Creed Unity leans Optimization (Practiced Mastery); Dark 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.
Assassin's Creed Unity
Refined parkour, still forgiving combat
Dark
Shadow-teleport timing matters but combat is clunky-forgiving
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
Dark
Guards run scripted patrol and alert routines
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
Dark
Patrols are fixed once observed
Dark leans a little harder on optimization, though the gap is small.
Assassin's Creed Unity
Gear builds and blackbox approach planning
Dark
Skill builds and patrol routing solve each stealth arena
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.
