head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

Execution · Pure Mechanics
Open-world arcade racer about boost and takedowns.

Execution · Pure Mechanics
Motion-controlled racing where fighting the Kinect is half the physical test.
Burnout Paradise leans Execution (Pure Mechanics); Sonic Free Riders leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Burnout Paradise
Boost timing, drift, takedown inputs
Sonic Free Riders
Full-body Kinect steering is a physical (if unreliable) motor test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Burnout Paradise
Mostly AI and sandbox driving
Sonic Free Riders
Human races add slight item-timing prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Burnout Paradise
Crash physics and traffic spawns
Sonic Free Riders
Item pickups inject kart-style randomness
Burnout Paradise leans a little harder on optimization, though the gap is small.
Burnout Paradise
Car collection and event routing
Sonic Free Riders
Track shortcuts are shallow 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.
