head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Practiced Mastery
Open-world western about an outlaw forced to hunt down his old gang.

Optimization · Practiced Mastery
A brawler RPG mixing style-switch combat with business-routing optimization.
Red Dead Redemption leans Execution (Practiced Mastery); Yakuza 0 leans Optimization (Practiced Mastery).
Red Dead Redemption leans a little harder on execution, though the gap is small.
Red Dead Redemption
Dead Eye softens but gunplay still wants aim
Yakuza 0
Brawler combat with style switching
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Red Dead Redemption
Multiplayer skirmishes add light human prediction
Yakuza 0
Scripted enemies
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Red Dead Redemption
Ambient events and spawns vary mildly
Yakuza 0
Minor drop randomness
Yakuza 0 leans a little harder on optimization, though the gap is small.
Red Dead Redemption
Mission approaches and economy are learnable
Yakuza 0
Skill tree, business mini-game routing
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.
