Execution · Practiced Mastery
The body-swapping driving game where you possess any car mid-chase.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.
Driver: San Francisco leans Execution (Practiced Mastery); Grand Theft Auto V leans Execution (Practiced Mastery).
Driver: San Francisco leans a little harder on execution, though the gap is small.
Driver: San Francisco
Car control still decides chases
Grand Theft Auto V
Driving and shooting demand decent inputs.
Grand Theft Auto V leans clearly harder on reads.
Driver: San Francisco
AI pursuits follow patterns
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Driver: San Francisco
Traffic variation only
Grand Theft Auto V
Some mission and lobby randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Driver: San Francisco
Shift ability creates solvable mission tactics
Grand Theft Auto V
Heists, money loops, builds learnable.
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.
