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

Optimization · Practiced Mastery
Greek-flavored action RPG where build-crafting drives long-haul play.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.
Assassin's Creed Odyssey 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 Odyssey
Parry and dodge timing required, not punishing.
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 Odyssey
Mercenary AI scripted, not adaptive.
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 Odyssey
Loot tiers and mercenary spawns randomized.
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Assassin's Creed Odyssey leans clearly harder on optimization.
Assassin's Creed Odyssey
Engravings, gear sets, builds 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.
