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

Optimization · Systems & Chaos
Lovecraftian card game where you decode occult mechanics by failing at them.

Optimization · Pure Optimization
An auto-battling deckbuilder about building a loop to defeat the Lich.
Cultist Simulator leans Optimization (Systems & Chaos); Loop Hero 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.
Cultist Simulator
only timer juggling on cards
Loop Hero
Autobattler, almost no inputs.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Cultist Simulator
no adaptive opponent
Loop Hero
Enemies follow scripts.
Cultist Simulator leans a little harder on variance, though the gap is small.
Cultist Simulator
opaque mechanics and card draws until mapped
Loop Hero
Card draws and loot drops randomize.
Loop Hero leans a little harder on optimization, though the gap is small.
Cultist Simulator
once decoded, the verb-card economy is solvable
Loop Hero
Deck and tile placement reward deep optimization.
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.
