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 · Systems & Chaos
A casual hidden-object adventure testing visual search and light puzzle solving.

Optimization · Pure Optimization
Telltale's episodic comedy adventure sending Guybrush Threepwood after a pox plaguing the Caribbean.
Clockwork Tales: Of Glass and Ink leans Optimization (Systems & Chaos); Tales of Monkey Island leans Optimization (Pure Optimization).
Clockwork Tales: Of Glass and Ink leans a little harder on execution, though the gap is small.
Clockwork Tales: Of Glass and Ink
Clicking hidden objects has no dexterity requirement
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.
Clockwork Tales: Of Glass and Ink
An authored steampunk plot with no adversary
Tales of Monkey Island
LeChuck and pirates are pure script.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Clockwork Tales: Of Glass and Ink
Object placements are unknown only until spotted
Tales of Monkey Island
Modern design telegraphs most puzzle information.
Tales of Monkey Island leans a little harder on optimization, though the gap is small.
Clockwork Tales: Of Glass and Ink
Hidden-object scenes and minigames have fixed findable solutions
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.
