head to head
Grand Theft Auto V asks more than Shrek 2, and the gap is reads.

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

Execution · Practiced Mastery
A forgiving licensed romp testing basic platforming and light puzzle solving.
Grand Theft Auto V leans Execution (Practiced Mastery); Shrek 2 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.
Shrek 2
Light platforming and enemy bashing with forgiving timing
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Shrek 2
Scripted movie-tie-in enemies never adapt to 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.
Shrek 2
Levels and puzzles are fixed once seen
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.
Shrek 2
Simple puzzle solutions and character-swap routing to learn
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.
