head to head
Grand Theft Auto V asks more than LEGO Star Wars: The Complete Saga, and the gap is execution.

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

Optimization · Practiced Mastery
All six Star Wars films compiled into one forgiving LEGO action-adventure collection.
Grand Theft Auto V leans Execution (Practiced Mastery); LEGO Star Wars: The Complete Saga leans Optimization (Practiced Mastery).
Grand Theft Auto V leans clearly harder on execution.
Grand Theft Auto V
Driving and shooting demand decent inputs.
LEGO Star Wars: The Complete Saga
Simple combat and jumps, death barely punished
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
LEGO Star Wars: The Complete Saga
Fixed enemy scripts, nothing models you
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
LEGO Star Wars: The Complete Saga
Deterministic levels with known secrets
LEGO Star Wars: The Complete Saga leans a little harder on optimization, though the gap is small.
Grand Theft Auto V
Heists, money loops, builds learnable.
LEGO Star Wars: The Complete Saga
Completion routing, stud multipliers and unlock order
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.
