head to head
Syphon Filter 3 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
Learning scripted mission layouts and executing aim and stealth under pressure.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Syphon Filter 3 leans Execution (Practiced Mastery).
Syphon Filter 3 leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Syphon Filter 3
Aim, taser timing and stealth movement carry encounters
Syphon Filter 3 leans a little harder on reads, though the gap is small.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Syphon Filter 3
Enemies run fixed scripts, never model the player
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
Syphon Filter 3
Enemy placements are scripted-but-unknown on first runs
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
Syphon Filter 3
Routes, gadget use and mission layouts are fully learnable
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.
