head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Light / Casual
A first-person mystery about a fire lookout in a Wyoming forest.

Optimization · Light / Casual
A short narrative drive testing curiosity about branching endings, not driving skill.
Firewatch leans Optimization (Light / Casual); Wheels of Aurelia leans Optimization (Light / Casual).
Wheels of Aurelia leans a little harder on execution, though the gap is small.
Firewatch
Walking and radio dialogue only.
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.
Firewatch
No adaptive opposition.
Wheels of Aurelia
Dialogue characters are authored, not adaptive
Wheels of Aurelia leans a little harder on variance, though the gap is small.
Firewatch
Minor environmental discoveries.
Wheels of Aurelia
Sixteen endings are hidden until routes are replayed
Wheels of Aurelia leans a little harder on optimization, though the gap is small.
Firewatch
Few systems to optimize.
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.
