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

Optimization · Practiced Mastery
Immersive sim where stacking powers and routes unlocks creative kills.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.
Dishonored 2 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.
Dishonored 2
Blink, parry, and aim timing matter.
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dishonored 2
Guards scripted; alert patterns fixed.
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.
Dishonored 2
Patrols and chaos rating vary lightly.
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Dishonored 2 leans clearly harder on optimization.
Dishonored 2
Powers, routes, ghost runs deeply solvable.
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.
