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 · Practiced Mastery
Cinematic survival action where scavenged resources and stealth carry you through the apocalypse.

Execution · Practiced Mastery
The first cinematic treasure-hunting adventure of cover shootouts and cliffside climbing.
The Last of Us leans Execution (Practiced Mastery); Uncharted: Drake's Fortune leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
The Last of Us
Aim, stealth timing, and scarce-ammo combat
Uncharted: Drake's Fortune
Cover gunfights and climbing timing
The Last of Us leans a little harder on reads, though the gap is small.
The Last of Us
Enemy AI searches but follows mappable routines
Uncharted: Drake's Fortune
Mercenary AI is scripted waves
The Last of Us leans a little harder on variance, though the gap is small.
The Last of Us
Encounter layouts unknown first time only
Uncharted: Drake's Fortune
Fully authored set pieces
The Last of Us leans a little harder on optimization, though the gap is small.
The Last of Us
Resource crafting and encounter routing
Uncharted: Drake's Fortune
Encounter layouts and weapon choices are learnable
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.
