head to head
Assassin's Creed Rogue asks more than Red Dead Redemption 2, and the gap is optimization.

Optimization · Practiced Mastery
An open-world stealth-action game where a turncoat assassin hunts his old brotherhood across the North Atlantic.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.
Assassin's Creed Rogue leans Optimization (Practiced Mastery); Red Dead Redemption 2 leans Execution (Practiced Mastery).
Red Dead Redemption 2 leans a little harder on execution, though the gap is small.
Assassin's Creed Rogue
Forgiving parkour and counter-heavy combat ask little
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.
Assassin's Creed Rogue
Stalker assassins ambush by script, not 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.
Assassin's Creed Rogue
Some naval weather and patrol noise
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Assassin's Creed Rogue leans clearly harder on optimization.
Assassin's Creed Rogue
Ship upgrades, fleet economy, and collectible routing dominate
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.
