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

Optimization · Pure Optimization
A comedy point-and-click testing lateral inventory-puzzle logic and nothing else.

Optimization · Pure Optimization
Telltale's episodic comedy adventure sending Guybrush Threepwood after a pox plaguing the Caribbean.
Sam & Max: Beyond Time and Space leans Optimization (Pure Optimization); Tales of Monkey Island 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.
Sam & Max: Beyond Time and Space
Pointing and clicking has no dexterity bar
Tales of Monkey Island
Click-driven; no physical demands.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Sam & Max: Beyond Time and Space
No adaptive opponent in a comedy adventure
Tales of Monkey Island
LeChuck and pirates are pure script.
Tales of Monkey Island leans a little harder on variance, though the gap is small.
Sam & Max: Beyond Time and Space
Puzzle states are visible or discoverable by poking
Tales of Monkey Island
Modern design telegraphs most puzzle information.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Sam & Max: Beyond Time and Space
Inventory-logic puzzles are the entire solvable test
Tales of Monkey Island
Episodic inventory puzzles each have one intended solution.
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.
