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 · Practiced Mastery
Black-and-white Wii brawler chasing stylish kills for points.
God of War III leans Execution (Pure Mechanics); MadWorld leans Execution (Practiced Mastery).
God of War III leans a little harder on execution, though the gap is small.
God of War III
Combo execution and QTE timing carry combat.
MadWorld
Motion-combo brawling and boss QTE timing
God of War III leans a little harder on reads, though the gap is small.
God of War III
Bosses fully scripted spectacle.
MadWorld
Enemies are scripted fodder
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.
MadWorld
Arenas are fixed
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
God of War III
Upgrade paths short and obvious.
MadWorld
Score multipliers reward creative kill routing
