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

Execution · Practiced Mastery
A fast solo FPS where managed aggression and weapon swapping sustain you.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.
Doom Eternal leans Execution (Practiced Mastery); Grand Theft Auto V leans Execution (Practiced Mastery).
Doom Eternal leans clearly harder on execution.
Doom Eternal
Weapon swapping and movement push the hands hard.
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.
Doom Eternal
Demon AI is scripted, 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.
Doom Eternal
Encounters are designed, not randomised.
Grand Theft Auto V
Some mission and lobby randomness.
Doom Eternal leans clearly harder on optimization.
Doom Eternal
Resource loops and weapon priority are solvable.
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.
