head to head
Duke Nukem 3D asks more than Grand Theft Auto: San Andreas, and the gap is execution.

Execution · Practiced Mastery
A fast shooter that rewards learning enemy ambush patterns and hunting interactable environments for secrets and shortcuts.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Duke Nukem 3D leans Execution (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
Duke Nukem 3D leans clearly harder on execution.
Duke Nukem 3D
Fast movement and precise shooting across interactive environments
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.
Duke Nukem 3D
All enemies follow scripted AI; no adaptive opponent present
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Duke Nukem 3D leans a little harder on variance, though the gap is small.
Duke Nukem 3D
Enemy ambushes and secret placement are hidden on first run
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.
Duke Nukem 3D
Level structure and secret routing reward systematic exploration
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.
