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
Refined sequel deepening Metro's stealth and moral undercurrents.

Execution · Practiced Mastery
Cinematic survival action where scavenged resources and stealth carry you through the apocalypse.
Metro: Last Light leans Execution (Practiced Mastery); The Last of Us 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.
Metro: Last Light
tighter gunplay than 2033, still deliberate
The Last of Us
Aim, stealth timing, and scarce-ammo combat
The Last of Us leans a little harder on reads, though the gap is small.
Metro: Last Light
scripted enemy encounters
The Last of Us
Enemy AI searches but follows mappable routines
Metro: Last Light leans a little harder on variance, though the gap is small.
Metro: Last Light
hidden morality system opaque first time
The Last of Us
Encounter layouts unknown first time only
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Metro: Last Light
stealth routes and resource management
The Last of Us
Resource crafting and encounter routing
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.
