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.

Optimization · Practiced Mastery
A storybook underwater metroidvania about a girl piloting a homemade submarine to find her father.

Execution · Practiced Mastery
Cinematic survival action where scavenged resources and stealth carry you through the apocalypse.
Song of the Deep leans Optimization (Practiced Mastery); The Last of Us leans Execution (Practiced Mastery).
The Last of Us leans a little harder on execution, though the gap is small.
Song of the Deep
Gentle submarine handling and claw manipulation
The Last of Us
Aim, stealth timing, and scarce-ammo combat
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Song of the Deep
Scripted sea creatures
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.
Song of the Deep
Unknown undersea map first dive
The Last of Us
Encounter layouts unknown first time only
Song of the Deep leans a little harder on optimization, though the gap is small.
Song of the Deep
Environmental puzzles and upgrade routing carry the game
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.
