head to head
Destiny 2 asks more than S.T.A.L.K.E.R.: Shadow of Chernobyl, and the gap is optimization.

Optimization · Practiced Mastery
A looter shooter where build optimization gates raid and seasonal content.

Optimization · Practiced Mastery
An atmospheric open-zone survival shooter set in the Chernobyl exclusion zone.
Destiny 2 leans Optimization (Practiced Mastery); S.T.A.L.K.E.R.: Shadow of Chernobyl leans Optimization (Practiced Mastery).
Destiny 2 leans a little harder on execution, though the gap is small.
Destiny 2
Gunplay matters but raids forgive mechanics.
S.T.A.L.K.E.R.: Shadow of Chernobyl
Ballistic gunplay punishes sloppy aim
Destiny 2 leans a little harder on reads, though the gap is small.
Destiny 2
PvE is scripted; Crucible has light adaptation.
S.T.A.L.K.E.R.: Shadow of Chernobyl
A-Life feels alive but doesn't model you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Destiny 2
Loot drops and rolls drive the chase.
S.T.A.L.K.E.R.: Shadow of Chernobyl
Anomalies, mutant spawns, and artifact RNG hide information
Destiny 2 leans clearly harder on optimization.
Destiny 2
Build crafting, mods, and damage rotations dominate.
S.T.A.L.K.E.R.: Shadow of Chernobyl
Artifact economy, routes, and stash knowledge converge
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.
