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

Optimization · Systems & Chaos
PS1 virtual-pet RPG where you raise, train, and evolve a Digimon whose growth follows hidden rules.

Optimization · Pure Optimization
A colorful loot ARPG where theorycrafting builds beats anything your hands do.
Digimon World leans Optimization (Systems & Chaos); Torchlight II leans Optimization (Pure Optimization).
Torchlight II leans a little harder on execution, though the gap is small.
Digimon World
Light real-time battle nudging and timing
Torchlight II
Faster combat asks for dodging and skill timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Digimon World
No adaptive opponent anywhere
Torchlight II
Enemies are scripted swarms, never adaptive
Digimon World leans a little harder on variance, though the gap is small.
Digimon World
Hidden evolution requirements and care mistakes dominate early play
Torchlight II
Loot rolls and random maps drive the chase
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Digimon World
Once requirements are mapped, raising becomes a solvable schedule
Torchlight II
Skill trees and gear synergies decide character power
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.
