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 family-friendly open-world driving adventure romping through Springfield's mystery of cameras and cola.

Execution · Practiced Mastery
The first cinematic treasure-hunting adventure of cover shootouts and cliffside climbing.
The Simpsons: Hit & Run leans Optimization (Practiced Mastery); Uncharted: Drake's Fortune leans Execution (Practiced Mastery).
Uncharted: Drake's Fortune leans a little harder on execution, though the gap is small.
The Simpsons: Hit & Run
Forgiving driving and light platforming
Uncharted: Drake's Fortune
Cover gunfights and climbing timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
The Simpsons: Hit & Run
No adaptive opposition exists
Uncharted: Drake's Fortune
Mercenary AI is scripted waves
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
The Simpsons: Hit & Run
Fixed missions with trivial traffic noise
Uncharted: Drake's Fortune
Fully authored set pieces
The Simpsons: Hit & Run leans a little harder on optimization, though the gap is small.
The Simpsons: Hit & Run
Mission routes, shortcuts, and collectible runs are solvable
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.
