head to head
Earthworm Jim 2 asks more than Grand Theft Auto: San Andreas, and the gap is execution.

Execution · Practiced Mastery
Sequel platformer that swaps genres per level but always tests the hands.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Earthworm Jim 2 leans Execution (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
Earthworm Jim 2 leans clearly harder on execution.
Earthworm Jim 2
Varied set-piece levels demand precise control
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Earthworm Jim 2
No adaptive opposition
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Grand Theft Auto: San Andreas leans a little harder on variance, though the gap is small.
Earthworm Jim 2
Deterministic levels and gimmicks
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Grand Theft Auto: San Andreas leans a little harder on optimization, though the gap is small.
Earthworm Jim 2
Learning each surreal level's fixed solution
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
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.
