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 LEGO arcade racer with transforming vehicles and item-based races.
Forza Horizon 3 leans Execution (Practiced Mastery); LEGO 2K Drive 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
LEGO 2K Drive
Drifting, boosting and transform timing reward skilled hands
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
LEGO 2K Drive
Online races add light human positioning play
LEGO 2K Drive leans a little harder on variance, though the gap is small.
Forza Horizon 3
Minor traffic and event variation
LEGO 2K Drive
Item pickups inject kart-racer randomness
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
LEGO 2K Drive
Vehicle builds and racing lines are learnable
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.
