head to head
Microsoft Flight Simulator (2020) 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
Global flight sim built on real weather and procedures.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Microsoft Flight Simulator (2020) leans Execution (Practiced Mastery).
Microsoft Flight Simulator (2020) leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Microsoft Flight Simulator (2020)
Procedure execution, instrument flying skill
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
Microsoft Flight Simulator (2020)
No adaptive opponents, ATC scripted
Microsoft Flight Simulator (2020) leans a little harder on variance, though the gap is small.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Microsoft Flight Simulator (2020)
Real weather and live traffic
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
Microsoft Flight Simulator (2020)
Flight planning, systems mastery, routing
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.
