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
Accessible car control amid demolition chaos rather than precision racing.

Execution · Practiced Mastery
An open-world arcade racer across Australia where car control and tuning carry every event.
Dirt Showdown leans Execution (Practiced Mastery); Forza Horizon 3 leans Execution (Practiced Mastery).
Forza Horizon 3 leans a little harder on execution, though the gap is small.
Dirt Showdown
Drifting, boosting and ramming need solid car control
Forza Horizon 3
Car control and racing lines at speed
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dirt Showdown
Demolition modes reward predicting human movement a little
Forza Horizon 3
Drivatars mimic but don't truly adapt
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dirt Showdown
Crash physics and pack chaos add randomness
Forza Horizon 3
Minor traffic and event variation
Forza Horizon 3 leans a little harder on optimization, though the gap is small.
Dirt Showdown
Event types and boost routes are quickly learnable
Forza Horizon 3
Tuning, car choice, and route knowledge
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.
