head to head
Grand Theft Auto V asks more than Kinect Star Wars, and the gap is reads.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.

Execution · Practiced Mastery
Motion-controlled spectacle testing little beyond gesture compliance.
Grand Theft Auto V leans Execution (Practiced Mastery); Kinect Star Wars leans Execution (Practiced Mastery).
Grand Theft Auto V leans a little harder on execution, though the gap is small.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Kinect Star Wars
Flailing gestures at the sensor is the only input test
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Kinect Star Wars
Everything on screen is scripted spectacle
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
Kinect Star Wars
Sequences replay identically
Grand Theft Auto V leans clearly harder on optimization.
Grand Theft Auto V
Heists, money loops, builds learnable.
Kinect Star Wars
Little system depth beyond gesture recognition quirks
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.
