head to head
The Last of Us asks more than Uncharted 4: A Thief's End, and the gap is optimization.

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

Execution · Practiced Mastery
Cinematic treasure-hunting where set pieces outshine systems.
The Last of Us leans Execution (Practiced Mastery); Uncharted 4: A Thief's End 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 4: A Thief's End
Cover shooting and platforming reward timing.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
The Last of Us
Enemy AI searches but follows mappable routines
Uncharted 4: A Thief's End
Scripted enemy AI throughout.
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 4: A Thief's End
Essentially no randomness.
The Last of Us leans clearly harder on optimization.
The Last of Us
Resource crafting and encounter routing
Uncharted 4: A Thief's End
Few systems to optimize beyond difficulty.
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.
