head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, 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
Tests patience with scripted encounters and light adventure-game routing.
Assassin's Creed II leans Optimization (Practiced Mastery); The Lord of the Rings: The Fellowship of the Ring 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 II
Counter-heavy combat stays forgiving
The Lord of the Rings: The Fellowship of the Ring
Basic melee, archery and stealth need only modest timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed II
Guards follow scripts
The Lord of the Rings: The Fellowship of the Ring
Enemies follow simple scripts; nothing adapts
The Lord of the Rings: The Fellowship of the Ring leans a little harder on variance, though the gap is small.
Assassin's Creed II
Fixed world and missions
The Lord of the Rings: The Fellowship of the Ring
Encounters are fixed; little is random once seen
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed II
Villa economy and route planning, lightly
The Lord of the Rings: The Fellowship of the Ring
Learning levels, item use and encounter order carries the game
