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
Open-world driving that tests car control with a tuning layer underneath.

Execution · Practiced Mastery
Seamless 3D platformer about collecting power cells across a precursor world.
Forza Horizon leans Execution (Practiced Mastery); Jak and Daxter: The Precursor Legacy leans Execution (Practiced Mastery).
Forza Horizon leans a little harder on execution, though the gap is small.
Forza Horizon
Driving skill with assists off carries every event
Jak and Daxter: The Precursor Legacy
Precise jumping and combo movement
Forza Horizon leans a little harder on reads, though the gap is small.
Forza Horizon
AI drivatars follow patterns; casual online adds little
Jak and Daxter: The Precursor Legacy
Lurkers follow set patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Horizon
The open world is fixed and fully discoverable
Jak and Daxter: The Precursor Legacy
Static seamless world
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Horizon
Car tuning and racing lines reward systematic study
Jak and Daxter: The Precursor Legacy
Power-cell routing across the connected world
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.
