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.

Execution · Light / Casual
A visual novel with light rhythm-based minigame segments.

Execution · Light / Casual
A collection of short stories about a family's strange deaths.
Symphonic Rain leans Execution (Light / Casual); What Remains of Edith Finch leans Execution (Light / Casual).
Symphonic Rain leans a little harder on execution, though the gap is small.
Symphonic Rain
light rhythm-timing input needed
What Remains of Edith Finch
Varied vignettes require light input skill.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Symphonic Rain
no opponent to out-predict
What Remains of Edith Finch
No adversaries.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Symphonic Rain
minor branching randomness
What Remains of Edith Finch
Stories are fixed.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Symphonic Rain
minimal systems beyond song mastery
What Remains of Edith Finch
Little to optimize.
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.
