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 · Practiced Mastery
Family-friendly dungeon crawler that swaps Minecraft's building for loot and hack-and-slash.

Optimization · Pure Optimization
Roguelite about raiding dungeons by night and pricing the loot in your shop by day.
Minecraft Dungeons leans Optimization (Practiced Mastery); Moonlighter 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.
Minecraft Dungeons
Dodge-rolls and kiting through mob swarms
Moonlighter
Dodge-heavy dungeon combat
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Minecraft Dungeons
Enemies are scripted hordes
Moonlighter
Enemies are scripted patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Minecraft Dungeons
Random loot and enchantment rolls drive power
Moonlighter
Random dungeon layouts and loot rolls
Moonlighter leans a little harder on optimization, though the gap is small.
Minecraft Dungeons
Gear synergies and enchant builds carry difficulty
Moonlighter
Price discovery and shop economy are the real game
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.
