head to head
Shadow of the Colossus 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 minimalist action adventure about toppling sixteen colossal puzzle-bosses.
Grand Theft Auto V leans Execution (Practiced Mastery); Shadow of the Colossus leans Optimization (Practiced Mastery).
Shadow of the Colossus leans a little harder on execution, though the gap is small.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Shadow of the Colossus
Climbing, grip management, and sword timing on moving giants.
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.
Shadow of the Colossus
Colossi follow fixed behavior patterns.
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
Shadow of the Colossus
Encounters play out nearly identically each attempt.
Shadow of the Colossus leans clearly harder on optimization.
Grand Theft Auto V
Heists, money loops, builds learnable.
Shadow of the Colossus
Each colossus is a solvable climbing puzzle.
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.
