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
Roguelite blending twin-stick shooting with tower-defense crystal escorts.

Optimization · Practiced Mastery
An atmospheric open-zone survival shooter set in the Chernobyl exclusion zone.
Endless Dungeon leans Execution (Practiced Mastery); S.T.A.L.K.E.R.: Shadow of Chernobyl leans Optimization (Practiced Mastery).
Endless Dungeon leans a little harder on execution, though the gap is small.
Endless Dungeon
Twin-stick shooting during wave defenses
S.T.A.L.K.E.R.: Shadow of Chernobyl
Ballistic gunplay punishes sloppy aim
S.T.A.L.K.E.R.: Shadow of Chernobyl leans a little harder on reads, though the gap is small.
Endless Dungeon
Monster waves follow spawn rules, not 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.
Endless Dungeon
Procedural floors and random resource rooms
S.T.A.L.K.E.R.: Shadow of Chernobyl
Anomalies, mutant spawns, and artifact RNG hide information
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Endless Dungeon
Turret placement and route economy planning
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.
