head to head
Grand Theft Auto V asks more than Rambo III, and the gap is reads.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.

Execution · Practiced Mastery
Retro run-and-gun reflexes over memorised level layouts and item routes.
Grand Theft Auto V leans Execution (Practiced Mastery); Rambo III leans Execution (Practiced Mastery).
Rambo III leans a little harder on execution, though the gap is small.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Rambo III
Shooting and dodging through enemy soldiers leads the test
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Rambo III
Guards follow simple fixed routines
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
Rambo III
Level layouts are static once seen
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto V
Heists, money loops, builds learnable.
Rambo III
Learning item locations and routes solves each mission
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.
