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

Execution · Practiced Mastery
First-person parkour against zombies, especially terrifying after dark.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Dying Light leans Execution (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
Dying Light leans clearly harder on execution.
Dying Light
Parkour traversal and melee timing demanding.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Dying Light leans a little harder on reads, though the gap is small.
Dying Light
Zombie AI scripted, non-adaptive.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dying Light
Night-hunter encounters bring randomness.
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.
Dying Light
Crafting, blueprints, skill trees solvable.
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.
