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

Optimization · Practiced Mastery
A quest-stuffed 2.5D platformer where a pink-haired wild boy bites evil pigs to undo their curses.
The Simpsons: Hit & Run leans Optimization (Practiced Mastery); Tomba! 2: The Evil Swine Return 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.
The Simpsons: Hit & Run
Forgiving driving and light platforming
Tomba! 2: The Evil Swine Return
Grab-and-throw platforming with moderate 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
Tomba! 2: The Evil Swine Return
Scripted pigs, no adaptation.
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
Tomba! 2: The Evil Swine Return
Fixed events; quests are deterministic.
Tomba! 2: The Evil Swine Return leans a little harder on optimization, though the gap is small.
The Simpsons: Hit & Run
Mission routes, shortcuts, and collectible runs are solvable
Tomba! 2: The Evil Swine Return
Interlocking 130-plus event quests reward sequencing.
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.
