head to head
Shadow of the Colossus asks more than Red Dead Redemption 2, and the gap is optimization.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.

Optimization · Practiced Mastery
A minimalist action adventure about toppling sixteen colossal puzzle-bosses.
Red Dead Redemption 2 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.
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Shadow of the Colossus
Climbing, grip management, and sword timing on moving giants.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Shadow of the Colossus
Colossi follow fixed behavior patterns.
Red Dead Redemption 2 leans a little harder on variance, though the gap is small.
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Shadow of the Colossus
Encounters play out nearly identically each attempt.
Shadow of the Colossus leans clearly harder on optimization.
Red Dead Redemption 2
Loadouts and routes solvable but loose.
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.
