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 road-trip narrative adventure about two brothers fleeing across America.

Variance · Light / Casual
An exploration of narrative branches that deliberately tests nothing.
Life is Strange 2 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.
Life is Strange 2
No mechanical challenge
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.
Life is Strange 2
No opponents
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.
Life is Strange 2
Branching consequences unknown until seen
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.
Life is Strange 2
Light optimal-choice layer toward preferred endings
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.
