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

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

Execution · Practiced Mastery
Dark-fantasy Doom-engine shooter trading shotguns for elven wands and tomes.
Grand Theft Auto V leans Execution (Practiced Mastery); Heretic leans Execution (Practiced Mastery).
Heretic leans a little harder on execution, though the gap is small.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Heretic
Classic FPS strafing and aim
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Heretic
Monsters follow fixed 90s AI
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
Heretic
Static level layouts
Heretic leans a little harder on optimization, though the gap is small.
Grand Theft Auto V
Heists, money loops, builds learnable.
Heretic
Secret hunting, item hoarding, and route knowledge
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.
