head to head
Super Paper Mario 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 puzzle-leaning platformer testing perspective-flip problem solving more than reflexes.
Red Dead Redemption 2 leans Execution (Practiced Mastery); Super Paper Mario leans Optimization (Practiced Mastery).
Red Dead Redemption 2 leans a little harder on execution, though the gap is small.
Red Dead Redemption 2

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.
Super Paper Mario

Super Paper Mario leans clearly harder on optimization.
Red Dead Redemption 2
Loadouts and routes solvable but loose.
Super Paper Mario
