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

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

Execution · Practiced Mastery
Day-glo traversal shooter where staying on rails and walls keeps your style and survival up.
Grand Theft Auto V leans Execution (Practiced Mastery); Sunset Overdrive leans Execution (Practiced Mastery).
Sunset Overdrive leans a little harder on execution, though the gap is small.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Sunset Overdrive
Grind-rail momentum and mid-air shooting reward clean hands
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Sunset Overdrive
Mutant hordes are pattern-driven, never adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto V
Some mission and lobby randomness.
Sunset Overdrive
Horde mode spawns mix things up slightly
Sunset Overdrive leans a little harder on optimization, though the gap is small.
Grand Theft Auto V
Heists, money loops, builds learnable.
Sunset Overdrive
Amp builds, traversal lines, and style multipliers are solvable
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.
