head to head
The Last of Us Part II 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
Brutal cinematic stealth-action sequel where execution under pressure decides fights.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); The Last of Us Part II leans Execution (Practiced Mastery).
The Last of Us Part II leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
The Last of Us Part II
Faster, more demanding combat and dodge timing
The Last of Us Part II leans a little harder on reads, though the gap is small.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
The Last of Us Part II
Smarter AI still runs mappable search scripts
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
The Last of Us Part II
First-encounter unknowns only
Grand Theft Auto: San Andreas 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
The Last of Us Part II
Crafting economy and encounter route planning
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.
