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

Execution · Practiced Mastery
Souls-flavored action-adventure where Fury whips through the Seven Deadly Sins on a ruined Earth.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.
Darksiders III leans Execution (Practiced Mastery); Grand Theft Auto V leans Execution (Practiced Mastery).
Darksiders III leans clearly harder on execution.
Darksiders III
Souls-style dodge timing with punishing windows carries fights
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.
Darksiders III
Sin bosses are pattern sets, not adaptive minds
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.
Darksiders III
Hidden upgrades matter once; world is fixed
Grand Theft Auto V
Some mission and lobby randomness.
Darksiders III leans clearly harder on optimization.
Darksiders III
Hollow swapping, upgrade routing, and moveset study pay off
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.
