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

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

Optimization · Practiced Mastery
A forgiving family collect-athon testing completionist puzzle-solving.
Grand Theft Auto V leans Execution (Practiced Mastery); LEGO Star Wars II: The Original Trilogy 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 II: The Original Trilogy
Forgiving combat and platforming for all ages
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 II: The Original Trilogy
Enemies are trivial fixed scripts
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 II: The Original Trilogy
Authored levels hold no real randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto V
Heists, money loops, builds learnable.
LEGO Star Wars II: The Original Trilogy
Minikit hunting and ability-gated puzzles are the depth
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.
