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
Ezio's Renaissance revenge tale of parkour, assassination, and villa-building across Italy.

Optimization · Practiced Mastery
A gentle physics puzzle-platformer starring a creature made of unraveling yarn.
Assassin's Creed II leans Optimization (Practiced Mastery); Unravel 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.

Counter-heavy combat stays forgiving
Unravel
Gentle platforming and yarn-swing timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Unravel
No opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed II
Fixed world and missions
Unravel
Everything is visible and fixed

Assassin's Creed II
Villa economy and route planning, lightly
Unravel
Physics puzzles with discoverable intended solutions
