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
Cinematic combo-action reboot of Castlevania in the God of War mold.

Optimization · Practiced Mastery
Zelda-flavoured musou where one hero mows down armies across Calamity-era Hyrule.
Castlevania: Lords of Shadow leans Execution (Practiced Mastery); Hyrule Warriors: Age of Calamity leans Optimization (Practiced Mastery).
Castlevania: Lords of Shadow leans a little harder on execution, though the gap is small.
Castlevania: Lords of Shadow
Combo timing, dodges, and QTE precision
Hyrule Warriors: Age of Calamity
Combo timing, dodges, and flurry-rush windows
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Castlevania: Lords of Shadow
Bosses and titans are fully scripted
Hyrule Warriors: Age of Calamity
Enemy hordes are scripted, never adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Castlevania: Lords of Shadow
Deterministic encounters
Hyrule Warriors: Age of Calamity
Minor drop randomness only
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Castlevania: Lords of Shadow
Combo unlocks and learning fixed movesets
Hyrule Warriors: Age of Calamity
Character builds, weapon fusion, and mission 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.
