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
An open-world arcade racer across Australia where car control and tuning carry every event.

Execution · Practiced Mastery
An open-world racing MMO about collecting cars and cruising Ibiza and Hawaii.
Forza Horizon 3 leans Execution (Practiced Mastery); Test Drive Unlimited 2 leans Execution (Practiced Mastery).
Forza Horizon 3 leans a little harder on execution, though the gap is small.
Forza Horizon 3
Car control and racing lines at speed
Test Drive Unlimited 2
Open-road car control decides races
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Horizon 3
Drivatars mimic but don't truly adapt
Test Drive Unlimited 2
Online rivals add mild jockeying
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Horizon 3
Minor traffic and event variation
Test Drive Unlimited 2
Traffic and weather add small noise
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Horizon 3
Tuning, car choice, and route knowledge
Test Drive Unlimited 2
Car choice, upgrades, and route knowledge compound
