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
A narrative mystery testing deduction by matching evidence against scripted lies.

Optimization · Pure Optimization
Building a team and exploiting type-matchup math against scripted trainers.
A Case of Distrust leans Optimization (Systems & Chaos); Pokémon LeafGreen Version leans Optimization (Pure Optimization).
Pokémon LeafGreen Version leans a little harder on execution, though the gap is small.
A Case of Distrust
Pure dialogue and menu selection
Pokémon LeafGreen Version
Menu-driven turn battles demand no physical skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
A Case of Distrust
Suspects lie by script, not in response to you
Pokémon LeafGreen Version
Trainers are scripted; link battles are a side mode
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
A Case of Distrust
The mystery is hidden information until evidence reveals it
Pokémon LeafGreen Version
Wild encounters, catch rolls and crits add mappable RNG
Pokémon LeafGreen Version leans a little harder on optimization, though the gap is small.
A Case of Distrust
Matching statements against evidence is a deduction puzzle
Pokémon LeafGreen Version
Type matchups and team building are the solvable core
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.
