head to head
Project Wingman 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
An indie love letter to arcade flight combat with relentless missile-dodging dogfights.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Project Wingman leans Execution (Practiced Mastery).
Project Wingman leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Project Wingman
Dense missile spam demands constant evasive flying and aim.
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
Project Wingman
Enemy aces are scripted set pieces.
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
Project Wingman
Fixed missions; conquest mode adds light randomness.
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
Project Wingman
Loadout choice and learned mission flow decide harder difficulties.
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.
