head to head
Donkey Kong 64 asks more than Red Dead Redemption 2, and the gap is optimization.

Optimization · Practiced Mastery
The N64 collectathon that buries five playable Kongs in collectibles.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.
Donkey Kong 64 leans Optimization (Practiced Mastery); Red Dead Redemption 2 leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Donkey Kong 64
Moderate platforming and minigame dexterity
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Red Dead Redemption 2 leans a little harder on reads, though the gap is small.
Donkey Kong 64
Scripted bosses and enemies
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Red Dead Redemption 2 leans a little harder on variance, though the gap is small.
Donkey Kong 64
Little randomness; secrets known once found
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Donkey Kong 64 leans clearly harder on optimization.
Donkey Kong 64
Routing five Kongs through collectible checklists
Red Dead Redemption 2
Loadouts and routes solvable but loose.
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.
