head to head
Yakuza 6: The Song of Life asks more than Red Dead Redemption 2, and the gap is optimization.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.

Optimization · Practiced Mastery
Kiryu's farewell chapter protecting a baby in seaside Onomichi.
Red Dead Redemption 2 leans Execution (Practiced Mastery); Yakuza 6: The Song of Life leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Yakuza 6: The Song of Life
Simplified Dragon Engine combat keeps a light timing test.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Yakuza 6: The Song of Life
Enemies follow fixed scripts.
Red Dead Redemption 2 leans a little harder on variance, though the gap is small.
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Yakuza 6: The Song of Life
Negligible randomness.
Yakuza 6: The Song of Life leans clearly harder on optimization.
Red Dead Redemption 2
Loadouts and routes solvable but loose.
Yakuza 6: The Song of Life
Stat feeding and heat upgrades are straightforward systems.
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.
