head to head
Nex Machina 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
A twin-stick arcade shooter where flawless movement through layered projectile patterns and human-rescue routing is the skill ceiling.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Nex Machina leans Execution (Practiced Mastery).
Nex Machina leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Nex Machina
Rapid dodging through layered lasers and bullets is the entire test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Nex Machina
All enemy behaviour is scripted arcade-style
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
Nex Machina
Enemy arrangement has minor randomisation between waves
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
Nex Machina
Human rescue routing and weapon pick sequencing reward study
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.
