head to head
Grand Theft Auto: San Andreas asks more than Shrek 2, and the gap is optimization.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.

Execution · Practiced Mastery
A forgiving licensed romp testing basic platforming and light puzzle solving.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Shrek 2 leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Shrek 2
Light platforming and enemy bashing with forgiving timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Shrek 2
Scripted movie-tie-in enemies never adapt to you
Grand Theft Auto: San Andreas leans a little harder on variance, though the gap is small.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Shrek 2
Levels and puzzles are fixed once seen
Grand Theft Auto: San Andreas leans clearly harder on optimization.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
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.
