head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
A grim 2D action metroidvania steeped in religious horror.

Execution · Practiced Mastery
Two Spider-Men, faster traversal, and deeper combo systems.
Blasphemous leans Execution (Practiced Mastery); Marvel's Spider-Man 2 leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous
Punishing 2D combat and platforming
Marvel's Spider-Man 2
Symbiote and dual-hero combat demands inputs.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous
Scripted bosses
Marvel's Spider-Man 2
Enemies scripted, not modeling player.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous
Static world
Marvel's Spider-Man 2
Light open-world randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous
Rosary bead builds and routing
Marvel's Spider-Man 2
Expanded skill trees and gadget combos solvable.
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.
