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
A puzzle-leaning platformer testing perspective-flip problem solving more than reflexes.
Assassin's Creed Unity leans Optimization (Practiced Mastery); Super Paper Mario 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
Super Paper Mario
Light platforming demands, well below mainline Mario
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
Super Paper Mario
Enemies follow simple fixed patterns, no adaptation
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
Super Paper Mario
Dimension-flip secrets are scripted-but-unknown until found
Super Paper Mario leans a little harder on optimization, though the gap is small.
Assassin's Creed Unity
Gear builds and blackbox approach planning
Super Paper Mario
Solving levels via the 2D/3D flip mechanic is the core test
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.
