head to head
Grand Theft Auto: San Andreas asks more than Sleeping Dogs, and the gap is optimization.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.

Execution · Practiced Mastery
An open-world crime game where combat combos and driving skill carry the action.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Sleeping Dogs leans Execution (Practiced Mastery).
Sleeping Dogs leans a little harder on execution, though the gap is small.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Sleeping Dogs
brawling and driving need timing/aim
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
Sleeping Dogs
scripted enemy AI, no adaptation
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
Sleeping Dogs
minor loot and traffic randomness
Grand Theft Auto: San Andreas leans clearly harder on optimization.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
Sleeping Dogs
upgrade paths and mission routes solvable
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.
