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.

Variance · Light / Casual
A branching musical narrative testing taste in choices rather than any skill.
Firewatch leans Optimization (Light / Casual); Stray Gods: The Roleplaying Musical leans Variance (Light / Casual).
Firewatch leans a little harder on execution, though the gap is small.
Firewatch
Walking and radio dialogue only.
Stray Gods: The Roleplaying Musical
Picking dialogue and song choices takes no skill
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.
Stray Gods: The Roleplaying Musical
Characters react on scripted branches, not adaptation
Stray Gods: The Roleplaying Musical leans a little harder on variance, though the gap is small.
Firewatch
Minor environmental discoveries.
Stray Gods: The Roleplaying Musical
Branch outcomes hidden until a choice lands
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Firewatch
Few systems to optimize.
Stray Gods: The Roleplaying Musical
Light persuasion-style stat picks, barely a system
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.
