head to head
Grand Theft Auto: San Andreas asks more than Far Cry 6, and the gap is optimization.

Execution · Practiced Mastery
Open-world guerrilla shooter built on outpost loops and gadgety guns.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Far Cry 6 leans Execution (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
Far Cry 6 leans a little harder on execution, though the gap is small.
Far Cry 6
Shooting and stealth timing standard.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Far Cry 6 leans a little harder on reads, though the gap is small.
Far Cry 6
Soldier AI fixed reactive patterns.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Far Cry 6
Patrols and outpost spawns vary.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Grand Theft Auto: San Andreas leans clearly harder on optimization.
Far Cry 6
Resolver weapons and loadouts learnable.
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.
