head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Optimization · Pure Optimization
Building a team and exploiting type-matchup math against scripted trainers.

Optimization · Systems & Chaos
A hidden-object escape adventure testing visual search and sequential puzzle logic.

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Pokémon LeafGreen Version
Menu-driven turn battles demand no physical skill
True Fear: Forsaken Souls Part 2
Clicking hidden objects needs no speed
Pokémon LeafGreen Version leans a little harder on reads, though the gap is small.
Pokémon LeafGreen Version
Trainers are scripted; link battles are a side mode
True Fear: Forsaken Souls Part 2
A fully scripted horror story, nothing adapts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.

Wild encounters, catch rolls and crits add mappable RNG
True Fear: Forsaken Souls Part 2
Object locations and story beats are unknown once
Pokémon LeafGreen Version leans a little harder on optimization, though the gap is small.
Pokémon LeafGreen Version
Type matchups and team building are the solvable core
True Fear: Forsaken Souls Part 2
Escape-room puzzle chains are the entire challenge
