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 · Practiced Mastery
Bleak road-trip shooter where every weapon levels up through use.

Execution · Practiced Mastery
Cinematic survival action where scavenged resources and stealth carry you through the apocalypse.
Resistance 3 leans Execution (Practiced Mastery); The Last of Us leans Execution (Practiced Mastery).
Resistance 3 leans a little harder on execution, though the gap is small.
Resistance 3
Precision shooting with health pickups punishing sloppy play.
The Last of Us
Aim, stealth timing, and scarce-ammo combat
Resistance 3 leans a little harder on reads, though the gap is small.
Resistance 3
Mostly scripted campaign; smaller multiplayer scene.
The Last of Us
Enemy AI searches but follows mappable routines
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Resistance 3
First-run encounter unknowns.
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.
Resistance 3
Weapon-leveling wheel rewards deliberate arsenal investment.
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.
