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
A kart-style racer about drifting and using items on family-friendly tracks.

Execution · Practiced Mastery
An open-world racer where vehicle handling across multiple disciplines carries the challenge.
Cars 3: Driven to Win leans Execution (Practiced Mastery); The Crew 2 leans Execution (Practiced Mastery).
The Crew 2 leans a little harder on execution, though the gap is small.
Cars 3: Driven to Win
drifting and item-timing control
The Crew 2
precise driving/flying/boating control
Cars 3: Driven to Win leans a little harder on reads, though the gap is small.
Cars 3: Driven to Win
minimal, mostly AI opponents
The Crew 2
AI racers scripted, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Cars 3: Driven to Win
item pickups and track hazard randomness
The Crew 2
weather and traffic add randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Cars 3: Driven to Win
vehicle upgrades and track knowledge
The Crew 2
vehicle tuning and routes solvable
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.
