head to head
Sifu 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
Drilling fixed enemy movesets until parry-perfect execution carries a run.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Sifu leans Execution (Practiced Mastery).
Sifu leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Sifu
Parry and dodge timing on tight windows is everything
Sifu leans a little harder on reads, though the gap is small.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Sifu
Enemies attack from fixed movesets, never adapt
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
Sifu
Levels are deterministic once learned
Sifu 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
Sifu
Learning movesets, shortcuts and the aging economy is the meta
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.
