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 · Practiced Mastery
Off-road simulator about hauling lumber through brutally deformable Russian mud.
Moonlighter leans Optimization (Pure Optimization); Spintires leans Optimization (Practiced Mastery).
Spintires leans a little harder on execution, though the gap is small.
Moonlighter
Dodge-heavy dungeon combat
Spintires
Throttle finesse and winching through mud need careful hands
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
Spintires
No opponents
Moonlighter leans a little harder on variance, though the gap is small.
Moonlighter
Random dungeon layouts and loot rolls
Spintires
Terrain deforms dynamically; fuel and routes uncertain until scouted
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
Spintires
Route choice, fuel logistics, and vehicle selection decide success
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.
