head to head
Super Mario 64 FPS 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.

Execution · Practiced Mastery
Familiar SM64 routing and movement re-tested with a gun in hand.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Super Mario 64 FPS leans Execution (Practiced Mastery).
Super Mario 64 FPS leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Super Mario 64 FPS
Platform movement plus aiming carries every star
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Super Mario 64 FPS
Recreated SM64 enemies follow original scripts
Grand Theft Auto: San Andreas leans a little harder on variance, though the gap is small.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Super Mario 64 FPS
Levels are known quantities from the source game
Grand Theft Auto: San Andreas leans a little harder on optimization, though the gap is small.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
Super Mario 64 FPS
Star routing and movement tech are well-mapped territory
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.
