Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Optimization · Pure Optimization
An action RPG that crowns you king and tests your treasury more than your sword.

Optimization · Pure Optimization
Optimising terror combos against scripted victims to maximise a points score per level.
Fable III leans Optimization (Pure Optimization); Naughty Bear leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Fable III
Simplified combat rarely punishes
Naughty Bear
Simple melee and chase inputs with low timing demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fable III
Scripted enemies
Naughty Bear
Victim bears run scripted panic routines, never modelling you
Naughty Bear leans a little harder on variance, though the gap is small.
Fable III
Largely fixed world
Naughty Bear
Bear patrols add mild unpredictability per attempt
Naughty Bear leans a little harder on optimization, though the gap is small.
Fable III
Treasury management and kingdom promises drive the endgame
Naughty Bear
Maximising scare-point combos per level is a solvable puzzle
