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.

Optimization · Pure Optimization
A genre-hopping adventure that evolves through gaming history as you play.

Optimization · Practiced Mastery
A brawler RPG mixing style-switch combat with business-routing optimization.
Evoland leans Optimization (Pure Optimization); Yakuza 0 leans Optimization (Practiced Mastery).
Yakuza 0 leans a little harder on execution, though the gap is small.
Evoland
Light Zelda-style action sections
Yakuza 0
Brawler combat with style switching
Yakuza 0 leans a little harder on reads, though the gap is small.
Evoland
No adaptive opponent
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.
Evoland
Some random encounters in RPG segments
Yakuza 0
Minor drop randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Evoland
Short, fully mappable progression gimmick
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.
