Grand Theft Auto IVvsSonic Free Riders
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Grand Theft Auto IV
Execution · Practiced Mastery
A grittier crime story where weighty driving and gunplay carry the experience.
Sonic Free Riders
Execution · Pure Mechanics
Motion-controlled racing where fighting the Kinect is half the physical test.
Grand Theft Auto IV leans Execution (Practiced Mastery); Sonic Free Riders leans Execution (Pure Mechanics).
Grand Theft Auto IVSonic Free Riders
Axis by axis
Execution5 vs 6
Sonic Free Riders leans a little harder on execution, though the gap is small.
Grand Theft Auto IV
Heavier driving and cover shooting reward control.
Sonic Free Riders
Full-body Kinect steering is a physical (if unreliable) motor test
Reads1 vs 1
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto IV
Scripted AI, no adaptive opponent modeling.
Sonic Free Riders
Human races add slight item-timing prediction
Variance2 vs 2
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto IV
Minor mission variance.
Sonic Free Riders
Item pickups inject kart-style randomness
Optimization3 vs 2
Grand Theft Auto IV leans a little harder on optimization, though the gap is small.
Grand Theft Auto IV
Mission routing and weapon picks learnable.
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.
