head to head
God of War Ragnarok asks more than Grand Theft Auto: San Andreas, and the gap is execution.

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

God of War Ragnarok leans clearly harder on execution.
God of War Ragnarok
Parry timing and combo execution in combat
Grand Theft Auto: San Andreas

God of War Ragnarok
Bosses use fixed movesets
Grand Theft Auto: San Andreas

God of War Ragnarok
Negligible randomness
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.
God of War Ragnarok
Build choices and moveset mastery solve bosses
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.
