head to head
Dark Souls asks more than Grand Theft Auto V, and the gap is execution.

Execution · Practiced Mastery
A precise action RPG about learning fixed boss patterns through punishing repetition.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.
Dark Souls leans Execution (Practiced Mastery); Grand Theft Auto V leans Execution (Practiced Mastery).
Dark Souls leans clearly harder on execution.
Dark Souls
Timing dodges and stamina control define every encounter.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Grand Theft Auto V leans a little harder on reads, though the gap is small.
Dark Souls
Bosses run fixed scripted movesets; not adaptive.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Dark Souls
Minor drop-rate randomness; otherwise deterministic world.
Grand Theft Auto V
Some mission and lobby randomness.
Dark Souls leans clearly harder on optimization.
Dark Souls
Builds, routes, and boss patterns are fully learnable.
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.
