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
Tests racing-line discipline and upgrade economy management on fixed real-world circuits.
Forza Horizon leans Execution (Practiced Mastery); Real Racing 3 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
Real Racing 3
Braking points and racing lines are pure motor skill
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
Real Racing 3
Time-shifted opponents are recordings, not adapting minds
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
Real Racing 3
Tracks are licensed and fully fixed
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
Real Racing 3
Car upgrades and the monetised economy demand managing
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.
