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

Execution · Light / Casual
A pack-in 3D platformer celebrating PlayStation history.

Execution · Light / Casual
A first-person horror about a journalist investigating an asylum.
Astro's Playroom leans Execution (Light / Casual); Outlast leans Execution (Light / Casual).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Astro's Playroom
Very forgiving platforming
Outlast
Running, hiding, and camera use.
Astro's Playroom leans a little harder on reads, though the gap is small.
Astro's Playroom
Scripted enemies
Outlast
Enemies follow scripts.
Outlast leans a little harder on variance, though the gap is small.
Astro's Playroom
Static levels
Outlast
Mild patrol variance.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Astro's Playroom
Collectible completion
Outlast
Battery and route planning shallow.
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.
