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 · Practiced Mastery
Fighting and building at insect scale by learning fixed creature patterns and optimising gear choices.

Optimization · Pure Optimization
Roguelite about raiding dungeons by night and pricing the loot in your shop by day.
Grounded leans Optimization (Practiced Mastery); Moonlighter leans Optimization (Pure Optimization).
Grounded leans a little harder on execution, though the gap is small.
Grounded
Bug combat demands precise dodge timing and weapon choice
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.
Grounded
Insect AI is scripted; no adaptive opponent
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.
Grounded
Creature spawn and loot drops carry session-level randomness
Moonlighter
Random dungeon layouts and loot rolls
Moonlighter leans a little harder on optimization, though the gap is small.
Grounded
Base placement, gear progression, and creature weaknesses are solvable
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.
