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

Variance · Light / Casual
A short horror walking sim that tests nothing but willingness to read the notes.

Variance · Light / Casual
An exploration of narrative branches that deliberately tests nothing.
Fingerbones leans Variance (Light / Casual); The Stanley Parable leans Variance (Light / Casual).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Fingerbones
Walking and reading notes - no dexterity involved
The Stanley Parable
Walking is the only input
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fingerbones
No opponent of any kind
The Stanley Parable
The narrator is a script, however much he pretends otherwise
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fingerbones
The story is hidden information revealed once
The Stanley Parable
Endings are hidden information until you wander into them
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fingerbones
Finding all notes is a trivial exploration checklist
The Stanley Parable
Finding all branches is a trivial checklist
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.
