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

Execution · Practiced Mastery
Arcade beat-em-up classic about brawling through Metro City's gangs.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.
Final Fight leans Execution (Practiced Mastery); Grand Theft Auto V leans Execution (Practiced Mastery).
Final Fight leans a little harder on execution, though the gap is small.
Final Fight
Crowd-control timing and throw spacing
Grand Theft Auto V
Driving and shooting demand decent inputs.
Grand Theft Auto V leans clearly harder on reads.
Final Fight
Thugs spawn and attack on scripts
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Final Fight
Minor enemy placement randomness
Grand Theft Auto V
Some mission and lobby randomness.
Final Fight leans a little harder on optimization, though the gap is small.
Final Fight
Memorising waves and damage-efficient patterns
Grand Theft Auto V
Heists, money loops, builds learnable.
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.
