head to head
Mega Man 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
Demanding platform execution plus a solvable boss-weakness ordering puzzle.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Mega Man leans Execution (Practiced Mastery).
Mega Man leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Mega Man
Pixel-precise jumps and shots against brutal fixed stages
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
Mega Man
Robot Masters cycle rigid 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
Mega Man
Nothing changes between attempts
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
Mega Man
Boss-order weakness routing is a known solvable layer
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.
