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.

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

Optimization · Pure Optimization
A 2D sandbox of procedurally generated planets driven by crafting progression.
Moonlighter leans Optimization (Pure Optimization); Starbound leans Optimization (Pure Optimization).
Moonlighter leans a little harder on execution, though the gap is small.
Moonlighter
Dodge-heavy dungeon combat
Starbound
Light platforming and combat, generous margins
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
Starbound
Procedural NPCs follow simple fixed behaviours
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
Starbound
Procedural planets and loot keep early exploration unknown
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Moonlighter
Price discovery and shop economy are the real game
Starbound
Gear tiers, farming, and progression routes dominate
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.
