head to head
Perfect Dark asks more than Red Dead Redemption 2, and the gap is execution.

Execution · Practiced Mastery
N64 spy FPS famed for gadget-heavy missions and bot-filled multiplayer.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.
Perfect Dark leans Execution (Practiced Mastery); Red Dead Redemption 2 leans Execution (Practiced Mastery).
Perfect Dark leans clearly harder on execution.
Perfect Dark
N64 manual aim and tight mission play
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Perfect Dark leans clearly harder on reads.
Perfect Dark
Multiplayer and clever sims add some human-style adaptation
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Perfect Dark
Mission scripting fixed once learned
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Perfect Dark leans a little harder on optimization, though the gap is small.
Perfect Dark
Objective routing on harder difficulty tiers
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.
