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

Optimization · Pure Optimization
Comedic point-and-click adventure of Guybrush Threepwood, hand-drawn at its peak.

Optimization · Pure Optimization
Methodically decoding intricate fixed mechanisms hidden in a puzzle dollhouse.
The Curse of Monkey Island leans Optimization (Pure Optimization); The Room 4: Old Sins leans Optimization (Pure Optimization).
The Room 4: Old Sins leans a little harder on execution, though the gap is small.
The Curse of Monkey Island
pointing and clicking only
The Room 4: Old Sins
Twisting mechanisms onscreen takes no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
The Curse of Monkey Island
no adaptive opponent
The Room 4: Old Sins
A fixed dollhouse of secrets; nothing adapts
The Curse of Monkey Island leans a little harder on variance, though the gap is small.
The Curse of Monkey Island
puzzle solutions unknown on first play, then fixed
The Room 4: Old Sins
Mechanisms are hidden information until discovered
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
The Curse of Monkey Island
inventory logic puzzles are fully solvable
The Room 4: Old Sins
Each puzzle box is a deterministic mechanism to decode
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.
