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

Execution · Light / Casual
A meditative underwater journey about swimming through gorgeous ocean vistas.

Execution · Light / Casual
Cozy slice-of-life game about delivering mail in a 1980s lakeside town.
ABZÛ leans Execution (Light / Casual); Lake leans Execution (Light / Casual).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
ABZÛ
Gentle swimming controls, no fail states
Lake
Just driving a mail truck calmly
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
ABZÛ
No opponents at all
Lake
No opposition exists
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
ABZÛ
Scripted reveals, minimal surprise
Lake
Story beats authored, nothing hidden that matters
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
ABZÛ
Linear path, nothing to solve
Lake
Dialogue choices, no systems to solve
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.
