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

Optimization · Pure Optimization
Minimalist transit puzzle; route topology under spawning pressure.
Digimon World leans Optimization (Systems & Chaos); Mini Metro 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.
Digimon World
Light real-time battle nudging and timing
Mini Metro
light real-time line-drawing
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
Mini Metro
no adversary
Digimon World leans a little harder on variance, though the gap is small.
Digimon World
Hidden evolution requirements and care mistakes dominate early play
Mini Metro
station spawn pattern
Mini Metro leans a little harder on optimization, though the gap is small.
Digimon World
Once requirements are mapped, raising becomes a solvable schedule
Mini Metro
line topology and routing
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.
