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
Wordless action-adventure where you rearrange a broken mechanical world.
Assassin's Creed II leans Optimization (Practiced Mastery); Hob 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
Hob
Dodge-roll combat and platforming with moderate 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
Hob
Creatures attack on fixed patterns
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
Hob
World secrets unknown until uncovered
Hob leans a little harder on optimization, though the gap is small.
Assassin's Creed II
Villa economy and route planning, lightly
Hob
World-transforming puzzles and upgrade routing carry the game
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.
