head to head
Darksiders III asks more than Grand Theft Auto: San Andreas, and the gap is execution.

Execution · Practiced Mastery
Souls-flavored action-adventure where Fury whips through the Seven Deadly Sins on a ruined Earth.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Darksiders III leans Execution (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
Darksiders III leans clearly harder on execution.
Darksiders III
Souls-style dodge timing with punishing windows carries fights
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Darksiders III leans a little harder on reads, though the gap is small.
Darksiders III
Sin bosses are pattern sets, not adaptive minds
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.
Darksiders III
Hidden upgrades matter once; world is fixed
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Darksiders III
Hollow swapping, upgrade routing, and moveset study pay off
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.
