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
Roguelike soulslike shooter with deep builds.

Execution · Twitch Chaos
An open-world survival shooter set in a hostile irradiated Zone full of anomalies and scarce supplies.
Remnant II leans Execution (Practiced Mastery); S.T.A.L.K.E.R. 2: Heart of Chornobyl leans Execution (Twitch Chaos).
Remnant II leans a little harder on execution, though the gap is small.
Remnant II
Soulslike dodges with gunplay timing
S.T.A.L.K.E.R. 2: Heart of Chornobyl
Lethal gunfights with recoil, bleed, and ballistics punish sloppy aim
Remnant II leans a little harder on reads, though the gap is small.
Remnant II
Bosses scripted, not adaptive
S.T.A.L.K.E.R. 2: Heart of Chornobyl
A-Life NPCs roam but never model the player adaptively
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Remnant II
Procedural worlds and gear rolls vary
S.T.A.L.K.E.R. 2: Heart of Chornobyl
Anomalies, emissions, stash rolls, and unknown Zone layouts hide information
Remnant II leans a little harder on optimization, though the gap is small.
Remnant II
Archetype builds and mod synergies deep
S.T.A.L.K.E.R. 2: Heart of Chornobyl
Artifact hunting, gear upkeep economy, and routing through the Zone
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.
