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
Guided detective clue-hunting with hidden answers and minimal challenge.

Optimization · Pure Optimization
Experimenting with doll abilities to uncover multiple solutions to fixed puzzles.
Murdered: Soul Suspect leans Optimization (Systems & Chaos); Stacking 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.
Murdered: Soul Suspect
Walking and clue-clicking; demon stealth is trivial
Stacking
Hopping between dolls requires no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Murdered: Soul Suspect
Demons follow simple fixed patrols
Stacking
Puzzle NPCs are static props, not minds
Murdered: Soul Suspect leans a little harder on variance, though the gap is small.
Murdered: Soul Suspect
Clues and case answers are hidden until found
Stacking
Doll abilities are hidden until tried once
Stacking leans a little harder on optimization, though the gap is small.
Murdered: Soul Suspect
Deduction sequences are guided puzzles with known answers
Stacking
Finding every solution per puzzle is the real challenge
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.
