head to head
Super Mario Bros.: The Lost Levels 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
The famously punishing Japanese sequel to Super Mario Bros., built for players who mastered the original.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Super Mario Bros.: The Lost Levels leans Execution (Practiced Mastery).
Super Mario Bros.: The Lost Levels leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Super Mario Bros.: The Lost Levels
Brutal precision jumps, poison mushrooms punish any input slip
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 Bros.: The Lost Levels
No adaptive opponent; everything is scripted
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 Bros.: The Lost Levels
Hidden blocks and warp zones until memorised
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
Super Mario Bros.: The Lost Levels
Level memorisation and warp routing are half the battle
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.
