Building comparison
head to head
Fable IIvsUndertale
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.
Fable II
Optimization · Practiced Mastery
An accessible action RPG of moral choices, property empires, and a loyal dog.
Undertale
Optimization · Pure Optimization
A scripted RPG where pattern-learning and pacifist routing carry you.
Fable II leans Optimization (Practiced Mastery); Undertale leans Optimization (Pure Optimization).

Fable II
One-button combat, forgiving by design
Undertale
Bullet-hell dodging in scripted patterns
Reads0 vs 1
Undertale leans a little harder on reads, though the gap is small.
Fable II
Scripted opposition
Undertale
NPCs follow fixed dialogue trees, not adaptive
Variance1 vs 1
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fable II
Fixed world with minor loot rolls
Undertale
Minimal randomness in encounters
Optimization6 vs 7
Undertale leans a little harder on optimization, though the gap is small.
Fable II
Property empire and job economy trivially exploitable
Undertale
Learning fixed boss patterns and mercy routes wins
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.
