head to head
Card Shark asks more than Grand Theft Auto: San Andreas, and the gap is execution.

Execution · Practiced Mastery
A dexterity-focused card-cheating game where executing sleight-of-hand maneuvers under time pressure is the primary test.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Card Shark leans Execution (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
Card Shark leans clearly harder on execution.
Card Shark
Cheating gestures require precise timing and sleight-of-hand inputs
Grand Theft Auto: San Andreas

Card Shark
NPC marks follow scripted reactions; not truly adaptive
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Card Shark leans a little harder on variance, though the gap is small.
Card Shark
Card distribution contains some hidden info but is secondary
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Grand Theft Auto: San Andreas leans a little harder on optimization, though the gap is small.
Card Shark
Learning optimal cheat sequences and tells is a solvable puzzle
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
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.
