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
A space-faring Call of Duty mixing jetpack multiplayer with a starfighter campaign.

Execution · Practiced Mastery
An action MMO where manual aim and dodge skill matter as much as build planning in both PvE and PvP.
Call of Duty: Infinite Warfare leans Execution (Pure Mechanics); New World: Aeternum leans Execution (Practiced Mastery).
Call of Duty: Infinite Warfare leans a little harder on execution, though the gap is small.
Call of Duty: Infinite Warfare
Wall-running and thrust jumps demand mechanical skill
New World: Aeternum
Active dodge-block-aim combat demands real twitch skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: Infinite Warfare
Human opponents reward movement prediction
New World: Aeternum
Open-world PvP wars and outpost rush involve adaptive opponents
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: Infinite Warfare
Spawn logic and lobby variance add noise
New World: Aeternum
Gear drops add variance but crafting reduces reliance on RNG
New World: Aeternum leans a little harder on optimization, though the gap is small.
Call of Duty: Infinite Warfare
Rig choice and movement routes are solvable
New World: Aeternum
Weapon mastery and territory control strategies are systematically 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.
