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
Prequel spectacle brawler notable for bolting a gladiatorial multiplayer arena onto Kratos combat.

Execution · Practiced Mastery
An action adventure rewarding combat timing against scripted boss patterns.
God of War: Ascension leans Execution (Practiced Mastery); God of War Ragnarok 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.
God of War: Ascension
Tether grabs and elemental blade swaps reward dexterity
God of War Ragnarok
Parry timing and combo execution in combat
God of War: Ascension leans a little harder on reads, though the gap is small.
God of War: Ascension
Multiplayer arenas add real human opposition, lightly populated
God of War Ragnarok
Bosses use fixed movesets
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
God of War: Ascension
Campaign is fully scripted spectacle
God of War Ragnarok
Negligible randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
God of War: Ascension
Elemental loadouts and MP builds are mappable
God of War Ragnarok
Build choices and moveset mastery solve bosses
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.
