head to head
NHL 23 asks more than Grand Theft Auto V, and the gap is reads.

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

Execution · Practiced Mastery
Stick-skill execution and opponent habit-reading over a solvable hockey meta.
Grand Theft Auto V leans Execution (Practiced Mastery); NHL 23 leans Execution (Practiced Mastery).
NHL 23 leans a little harder on execution, though the gap is small.
Grand Theft Auto V
Driving and shooting demand decent inputs.
NHL 23
Skill-stick dekes and shot timing carry possession play
NHL 23 leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
NHL 23
Online opponents reward reading defensive structure habits
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.
NHL 23
Bounces, deflections and goalie AI add noise
NHL 23 leans a little harder on optimization, though the gap is small.
Grand Theft Auto V
Heists, money loops, builds learnable.
NHL 23
Meta builds, line chemistry and set plays are studyable
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.
