head to head
Silent Hill 2 Remake asks more than Grand Theft Auto V, and the gap is optimization.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.
Optimization · Practiced Mastery
A psychological horror balancing combat timing with resource discipline.
Grand Theft Auto V leans Execution (Practiced Mastery); Silent Hill 2 Remake leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Silent Hill 2 Remake
Combat timing and aim matter modestly
Grand Theft Auto V leans a little harder on reads, though the gap is small.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Silent Hill 2 Remake
Monsters follow fixed scripts
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.
Silent Hill 2 Remake
Some encounter and item randomness
Silent Hill 2 Remake leans clearly harder on optimization.
Grand Theft Auto V
Heists, money loops, builds learnable.
Silent Hill 2 Remake
Resource conservation and puzzle solving dominate
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.
