head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

Optimization · Practiced Mastery
Solving fixed gravity-manipulation puzzles with light physics platforming.

Optimization · Practiced Mastery
A family-friendly open-world driving adventure romping through Springfield's mystery of cameras and cola.
Rochard leans Optimization (Practiced Mastery); The Simpsons: Hit & Run leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Rochard
Light platforming and aimed throws, rarely demanding
The Simpsons: Hit & Run
Forgiving driving and light platforming
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Rochard
Guards follow simple scripts, never adapt
The Simpsons: Hit & Run
No adaptive opposition exists
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Rochard
Puzzle rooms are fixed and visible
The Simpsons: Hit & Run
Fixed missions with trivial traffic noise
Rochard leans a little harder on optimization, though the gap is small.
Rochard
Gravity-manipulation puzzles each have a findable solution
The Simpsons: Hit & Run
Mission routes, shortcuts, and collectible runs are solvable
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.
