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 grim 2D action metroidvania steeped in religious horror.

Execution · Practiced Mastery
A cinematic desert-bound adventure of shootouts, brawls, and sinking-ship set pieces.
Blasphemous leans Execution (Practiced Mastery); Uncharted 3: Drake's Deception leans Execution (Practiced Mastery).
Blasphemous leans a little harder on execution, though the gap is small.
Blasphemous
Punishing 2D combat and platforming
Uncharted 3: Drake's Deception
Gunfights, melee, and chases need steady hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous
Scripted bosses
Uncharted 3: Drake's Deception
Scripted enemies; multiplayer adds a trace
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Blasphemous
Static world
Uncharted 3: Drake's Deception
Linear authored adventure
Blasphemous leans a little harder on optimization, though the gap is small.
Blasphemous
Rosary bead builds and routing
Uncharted 3: Drake's Deception
Learning encounters and routes solves the campaign
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.
