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

Optimization · Practiced Mastery
A co-op looter shooter where aggressive ability builds and gear mods carry you through escalating expeditions.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.
Outriders 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.
Outriders
Cover shooting and ability 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.
Outriders
AI hordes are scripted aggression
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Outriders leans a little harder on variance, though the gap is small.
Outriders
Loot rolls gate the build chase
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Outriders leans clearly harder on optimization.
Outriders
Class builds and mod stacking dominate endgame
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.
