head to head
Anthem asks more than Grand Theft Auto: San Andreas, and the gap is variance.

Optimization · Practiced Mastery
A co-op looter shooter about flying exosuit javelins through a hostile alien frontier.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Anthem leans Optimization (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Anthem
Flight and shooting matter but are forgiving
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Anthem
Enemy AI is scripted
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Anthem leans clearly harder on variance.
Anthem
Loot rolls gate power
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Anthem
Javelin builds and loadout grinding dominate
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.
