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
A dense layered puzzle game demanding methodical inventory and dialogue optimization across four islands.

Optimization · Pure Optimization
A hidden-object adventure about searching scenes and solving fixed puzzles.
Monkey Island 2: LeChuck's Revenge leans Optimization (Pure Optimization); Mystery Case Files: 13th Skull 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.
Monkey Island 2: LeChuck's Revenge
Interface is point-and-click; no timing or precision required
Mystery Case Files: 13th Skull
Pointing and clicking, no twitch demand
Mystery Case Files: 13th Skull leans a little harder on reads, though the gap is small.
Monkey Island 2: LeChuck's Revenge
All puzzles are scripted; no opponent models the player
Mystery Case Files: 13th Skull
No adaptive opponent, puzzles are fixed
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Monkey Island 2: LeChuck's Revenge
Some item locations are initially hidden but deterministic
Mystery Case Files: 13th Skull
Hidden-object locations unknown until searched
Monkey Island 2: LeChuck's Revenge leans a little harder on optimization, though the gap is small.
Monkey Island 2: LeChuck's Revenge
Multi-step puzzle chains reward systematic item and dialogue mapping
Mystery Case Files: 13th Skull
Solving puzzles and finding objects is the whole loop
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.
