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

Execution · Practiced Mastery
Columbia's sky-rail shooter wrapped in dimensional intrigue.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
BioShock Infinite leans Execution (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
BioShock Infinite leans a little harder on execution, though the gap is small.
BioShock Infinite
Skyline traversal and aiming reward inputs.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
BioShock Infinite leans a little harder on reads, though the gap is small.
BioShock Infinite
Enemies scripted in arena waves.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Grand Theft Auto: San Andreas leans a little harder on variance, though the gap is small.
BioShock Infinite
Loot drops mildly randomized.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Grand Theft Auto: San Andreas leans clearly harder on optimization.
BioShock Infinite
Gear, vigors, weapon picks straightforward.
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.
