head to head
New Super Mario Bros. 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
Modern 2D Mario platformer built on classic jump precision and hidden exits.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); New Super Mario Bros. leans Execution (Practiced Mastery).
New Super Mario Bros. leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
New Super Mario Bros.
Jump timing and momentum control carry every level
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
New Super Mario Bros.
Enemies follow fixed scripted patterns
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
New Super Mario Bros.
Levels fully deterministic once seen
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
New Super Mario Bros.
Secret exits, star coins, and route knowledge
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.
