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
Cheerful physics platformer about a kicking blob toppling a capitalist conspiracy.

Execution · Practiced Mastery
The PlayStation Vita Uncharted, a portable cinematic treasure hunt with touch controls.
Pikuniku leans Execution (Light / Casual); Uncharted: Golden Abyss leans Execution (Practiced Mastery).
Uncharted: Golden Abyss leans a little harder on execution, though the gap is small.
Pikuniku
Floppy kicks and hops, gently imprecise
Uncharted: Golden Abyss
Touch-assisted gunplay and climbing, gentler demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Pikuniku
No adversary anywhere
Uncharted: Golden Abyss
Scripted enemy encounters only
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Pikuniku
Short authored world with few surprises
Uncharted: Golden Abyss
Linear handheld adventure
Uncharted: Golden Abyss leans a little harder on optimization, though the gap is small.
Pikuniku
Simple puzzles with obvious solutions
Uncharted: Golden Abyss
Collectible hunting and encounter knowledge
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.
