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
An action MMO where manual aim and dodge skill matter as much as build planning in both PvE and PvP.

Execution · Practiced Mastery
A cover-shooter Rainbow Six blending tactical room-clearing with solid gunplay.
New World: Aeternum leans Execution (Practiced Mastery); Tom Clancy's Rainbow Six: Vegas 2 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.
New World: Aeternum
Active dodge-block-aim combat demands real twitch skill
Tom Clancy's Rainbow Six: Vegas 2
Cover-based gunfights still punish poor aim
New World: Aeternum leans a little harder on reads, though the gap is small.
New World: Aeternum
Open-world PvP wars and outpost rush involve adaptive opponents
Tom Clancy's Rainbow Six: Vegas 2
Multiplayer brings some human adaptation; AI is scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
New World: Aeternum
Gear drops add variance but crafting reduces reliance on RNG
Tom Clancy's Rainbow Six: Vegas 2
Enemy placements partially unknown per encounter
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
New World: Aeternum
Weapon mastery and territory control strategies are systematically solvable
Tom Clancy's Rainbow Six: Vegas 2
Room-clearing order and squad commands are solvable tactics
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.
