head to head
Mad Dog McCree 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
Lightgun quick-draw reflexes against memorisable filmed ambush sequences.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Mad Dog McCree leans Execution (Practiced Mastery).
Mad Dog McCree leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Mad Dog McCree
Quick-draw lightgun accuracy under strict timers
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
Mad Dog McCree
Outlaws appear in filmed, fixed sequences
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Mad Dog McCree
Some ambush order shuffling, quickly mapped
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
Mad Dog McCree
Memorising who pops out where is the real progression
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.
