head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, 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 drift racing testing flowing car control and memorised optimal lines.
Forza Horizon leans Execution (Practiced Mastery); OutRun 2006: Coast 2 Coast 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
OutRun 2006: Coast 2 Coast
Sustained drift control at speed is the heart of it
Forza Horizon leans a little harder on reads, though the gap is small.
Forza Horizon
AI drivatars follow patterns; casual online adds little
OutRun 2006: Coast 2 Coast
Traffic is patterned, not predictive
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
OutRun 2006: Coast 2 Coast
Route branches you choose yourself - nothing hidden
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
OutRun 2006: Coast 2 Coast
Perfect drift lines and route choice are learnable theory
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.
