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 · Pure Mechanics
Spectacle hack-and-slash where reflexes and combo flow drive every fight.

Execution · Pure Mechanics
A Touhou fan metroidvania where a time-stopping maid weaves through scripted bullet hell.
God of War III leans Execution (Pure Mechanics); Touhou Luna Nights leans Execution (Pure Mechanics).
Touhou Luna Nights leans a little harder on execution, though the gap is small.
God of War III
Combo execution and QTE timing carry combat.
Touhou Luna Nights
Bullet-pattern dodging and time-stop knife play demand sharp hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
God of War III
Bosses fully scripted spectacle.
Touhou Luna Nights
Boss patterns are fully scripted danmaku
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
God of War III
Almost no randomness.
Touhou Luna Nights
Fixed level layouts, little hidden randomness
Touhou Luna Nights leans a little harder on optimization, though the gap is small.
God of War III
Upgrade paths short and obvious.
Touhou Luna Nights
Learning patterns and time-stop resource management
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.
