head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

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

Execution · Practiced Mastery
Zelda-meets-God-of-War action adventure starring the horseman War.
Blasphemous leans Execution (Practiced Mastery); Darksiders 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
Darksiders
combo-driven combat with dodge timing
Blasphemous leans a little harder on reads, though the gap is small.
Blasphemous
Scripted bosses
Darksiders
enemies are scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous
Static world
Darksiders
world and bosses are fixed
Darksiders leans a little harder on optimization, though the gap is small.
Blasphemous
Rosary bead builds and routing
Darksiders
Zelda-style dungeons and upgrade 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.
