head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Light / Casual
A narrative horror-investigation game where uncovering the mystery outweighs any mechanical challenge.

Optimization · Light / Casual
A serene open-world exploration about a coming-of-age desert pilgrimage.
Call of Cthulhu leans Optimization (Light / Casual); Sable leans Optimization (Light / Casual).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Cthulhu
light stealth timing, mostly minor
Sable
Gliding and climbing are gentle.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Cthulhu
no opponents, narrative investigation
Sable
No adversaries.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Cthulhu
skill checks add randomness
Sable
Open-world discoveries vary little.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Cthulhu
stat allocation lightly solvable
Sable
Quest routing has shallow optimization.
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.
