head to head
Payday: The Heist 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
Co-op FPS about four masked crooks holding out through scripted heist assaults.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Payday: The Heist leans Execution (Practiced Mastery).
Payday: The Heist leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Payday: The Heist
Holding off assault waves takes solid gunplay
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
Payday: The Heist
Police waves are scripted spawns
Payday: The Heist leans clearly harder on variance.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Payday: The Heist
Drill failures and objective locations shuffle
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
Payday: The Heist
Crew positioning and objective sequencing per heist
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.
