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 gritty crime shooter following two doomed mercenaries through botched heists.

Execution · Pure Mechanics
Motion-controlled racing where fighting the Kinect is half the physical test.
Kane & Lynch: Dead Men leans Execution (Practiced Mastery); Sonic Free Riders leans Execution (Pure Mechanics).
Sonic Free Riders leans a little harder on execution, though the gap is small.
Kane & Lynch: Dead Men
Cover shooting accuracy under pressure
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.
Kane & Lynch: Dead Men
Fragile Alliance betrayals add faint human guessing
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.
Kane & Lynch: Dead Men
Set-piece encounters vary little
Sonic Free Riders
Item pickups inject kart-style randomness
Kane & Lynch: Dead Men leans a little harder on optimization, though the gap is small.
Kane & Lynch: Dead Men
Squad orders and encounter knowledge
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.
