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 · Systems & Chaos
A kid-friendly mystery adventure testing light deduction over scripted cases.

Variance · Light / Casual
A narrative horror experience testing curiosity more than any skill axis.
Detective Pikachu leans Optimization (Systems & Chaos); MiSide leans Variance (Light / Casual).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Detective Pikachu
Tapping through investigation scenes asks nothing
MiSide
Walking and minigames make light physical demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Detective Pikachu
Witnesses are scripted, never adapting to you
MiSide
Mita is a scripted character, not an adaptive mind
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Detective Pikachu
Case facts are hidden until testimony reveals them
MiSide
Story surprises are hidden only until experienced
Detective Pikachu leans a little harder on optimization, though the gap is small.
Detective Pikachu
Assembling clues into conclusions is gentle fixed logic
MiSide
Linear narrative with simple puzzles to step through
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.
