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.

Variance · Light / Casual
A narrative horror experience testing curiosity more than any skill axis.

Optimization · Systems & Chaos
Guided detective clue-hunting with hidden answers and minimal challenge.
MiSide leans Variance (Light / Casual); Murdered: Soul Suspect leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
MiSide
Walking and minigames make light physical demands
Murdered: Soul Suspect
Walking and clue-clicking; demon stealth is trivial
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
MiSide
Mita is a scripted character, not an adaptive mind
Murdered: Soul Suspect
Demons follow simple fixed patrols
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
MiSide
Story surprises are hidden only until experienced
Murdered: Soul Suspect
Clues and case answers are hidden until found
Murdered: Soul Suspect leans a little harder on optimization, though the gap is small.
MiSide
Linear narrative with simple puzzles to step through
Murdered: Soul Suspect
Deduction sequences are guided puzzles with known answers
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.
