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

Execution · Practiced Mastery
Open-world driving that tests car control with a tuning layer underneath.

Execution · Practiced Mastery
Arcade car control at speed over memorised tracks with scripted police pressure.
Forza Horizon leans Execution (Practiced Mastery); Need for Speed: Hot Pursuit 2 leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Horizon
Driving skill with assists off carries every event
Need for Speed: Hot Pursuit 2
High-speed cornering and traffic dodging are the whole test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Horizon
AI drivatars follow patterns; casual online adds little
Need for Speed: Hot Pursuit 2
AI racers and cops follow rubber-band scripts
Need for Speed: Hot Pursuit 2 leans a little harder on variance, though the gap is small.
Forza Horizon
The open world is fixed and fully discoverable
Need for Speed: Hot Pursuit 2
Cop spawns and traffic add mild run-to-run noise
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
Need for Speed: Hot Pursuit 2
Track knowledge and racing lines are learnable and fixed
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.
