head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

Optimization · Systems & Chaos
A cosy-eldritch fishing game about hauling secrets from dark water.

Optimization · Pure Optimization
A gothic horror RPG blending survival-horror atmosphere with tactical grid battles in a haunted Welsh monastery.
DREDGE leans Optimization (Systems & Chaos); Koudelka leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
DREDGE
Fishing minigames and night dodging, light demands
Koudelka
Turn-based grid combat, no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
DREDGE
Horrors follow fixed rules
Koudelka
Monsters act on simple fixed logic
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
DREDGE
Fish spawns and fog-of-dread unknowns until mapped
Koudelka
Random encounters and drop rolls
Koudelka leans a little harder on optimization, though the gap is small.
DREDGE
Cargo tetris, routes, and upgrades reward planning
Koudelka
Stat allocation and durability planning decide fights
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.
