head to head
Red Dead Redemption 2 asks more than The Simpsons Game, and the gap is execution.

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

Optimization · Practiced Mastery
A gag-driven platformer testing little beyond collectible patience.
Red Dead Redemption 2 leans Execution (Practiced Mastery); The Simpsons Game leans Optimization (Practiced Mastery).
Red Dead Redemption 2 leans clearly harder on execution.
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
The Simpsons Game
Simple platforming and character-power timing
Red Dead Redemption 2 leans a little harder on reads, though the gap is small.
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
The Simpsons Game
Parody enemies are jokes on rails
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.
The Simpsons Game
Levels are fixed gag sequences
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Red Dead Redemption 2
Loadouts and routes solvable but loose.
The Simpsons Game
Character-ability puzzles and collectibles are lightly solvable
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.
