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 short narrative drive testing curiosity about branching endings, not driving skill.
Call of Cthulhu leans Optimization (Light / Casual); Wheels of Aurelia 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
Wheels of Aurelia
Steering is loose and outcomes barely depend on it
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
Wheels of Aurelia
Dialogue characters are authored, not adaptive
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
Wheels of Aurelia
Sixteen endings are hidden until routes are replayed
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
Wheels of Aurelia
Mapping which choices and routes trigger endings is light puzzle work
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.
