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 · Pure Optimization
A classic psychological adventure where an amnesiac navigates surreal delusions to recover his identity.

Optimization · Pure Optimization
Comedic point-and-click adventure of Guybrush Threepwood, hand-drawn at its peak.
Sanitarium leans Optimization (Pure Optimization); The Curse of Monkey Island leans Optimization (Pure Optimization).
Sanitarium leans a little harder on execution, though the gap is small.
Sanitarium
Point-and-click navigation requires no dexterity
The Curse of Monkey Island
pointing and clicking only
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Sanitarium
No opponents; the delusions follow a fixed narrative
The Curse of Monkey Island
no adaptive opponent
The Curse of Monkey Island leans a little harder on variance, though the gap is small.
Sanitarium
Surreal puzzle logic is unknown until reasoned out
The Curse of Monkey Island
puzzle solutions unknown on first play, then fixed
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Sanitarium
Every chapter is a deterministic puzzle to solve
The Curse of Monkey Island
inventory logic puzzles are fully solvable
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.
