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
Telltale's episodic comedy adventure sending Guybrush Threepwood after a pox plaguing the Caribbean.

Optimization · Pure Optimization
A LucasArts sci-fi adventure where astronauts stranded on an alien world puzzle out its dead civilization.
Tales of Monkey Island leans Optimization (Pure Optimization); The Dig 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.
Tales of Monkey Island
Click-driven; no physical demands.
The Dig
Point-and-click; no reflex demands.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Tales of Monkey Island
LeChuck and pirates are pure script.
The Dig
Alien world is static; companions follow scripts.
The Dig leans a little harder on variance, though the gap is small.
Tales of Monkey Island
Modern design telegraphs most puzzle information.
The Dig
Alien machinery's purpose is hidden until experimented with.
The Dig leans a little harder on optimization, though the gap is small.
Tales of Monkey Island
Episodic inventory puzzles each have one intended solution.
The Dig
Machine puzzles have single fixed solutions to deduce.
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.
