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

Optimization · Practiced Mastery
Comedy RPG where every turn-based attack hides an action-timing minigame.

Optimization · Practiced Mastery
Remake of the original Yakuza following Kiryu's return to Kamurocho.
Mario & Luigi: Superstar Saga leans Optimization (Practiced Mastery); Yakuza Kiwami 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.
Mario & Luigi: Superstar Saga
Timed hits and dodge jumps every turn
Yakuza Kiwami
Brawling combos and dodges are forgiving but present.
Yakuza Kiwami leans a little harder on reads, though the gap is small.
Mario & Luigi: Superstar Saga
Bosses telegraph fixed patterns
Yakuza Kiwami
Majima ambushes are scripted, not adaptive.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mario & Luigi: Superstar Saga
Encounters are authored
Yakuza Kiwami
Minor randomness in encounters and minigames.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Mario & Luigi: Superstar Saga
Bros. Attack mastery and stat builds
Yakuza Kiwami
Style upgrades, heat moves and gear are learnable 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.
