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
A precision metroidvania about learning fixed boss patterns and tight platforming.

Execution · Practiced Mastery
Dash-precision platforming with solvable boss orders and upgrade routing.
Hollow Knight leans Execution (Practiced Mastery); Mega Man X5 leans Execution (Practiced Mastery).
Hollow Knight leans a little harder on execution, though the gap is small.
Hollow Knight
Precise platforming and pogo timing dominate hard content.
Mega Man X5
Dash-jump precision and boss dodge timing demand clean hands
Hollow Knight leans a little harder on reads, though the gap is small.
Hollow Knight
Bosses run scripted attack pools; not adaptive.
Mega Man X5
Mavericks cycle fixed attack patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Hollow Knight
Negligible; world layout is fixed.
Mega Man X5
Random ending triggers add rare unmapped outcomes
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Hollow Knight
Charm builds and boss routes are fully learnable.
Mega Man X5
Armor parts, boss order and route knowledge solve the game
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.
