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 · Pure Optimization
Roguelite about raiding dungeons by night and pricing the loot in your shop by day.

Optimization · Practiced Mastery
A dungeon-crawler spin-off testing build management across randomised otherworlds.
Moonlighter leans Optimization (Pure Optimization); Silent Hill: Book of Memories leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Moonlighter
Dodge-heavy dungeon combat
Silent Hill: Book of Memories
Twin-stick melee and dodge timing matter moderately
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Moonlighter
Enemies are scripted patterns
Silent Hill: Book of Memories
Monsters follow simple scripted aggression
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Moonlighter
Random dungeon layouts and loot rolls
Silent Hill: Book of Memories
Procedural dungeon layouts and loot rolls vary each run
Moonlighter leans a little harder on optimization, though the gap is small.
Moonlighter
Price discovery and shop economy are the real game
Silent Hill: Book of Memories
Karma builds, weapon upkeep and puzzle rooms reward system mastery
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.
