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
On-rails photography game about provoking and capturing the perfect Pokémon shot.

Optimization · Practiced Mastery
Off-road simulator about hauling lumber through brutally deformable Russian mud.
Pokémon Snap leans Optimization (Pure Optimization); Spintires leans Optimization (Practiced Mastery).
Spintires leans a little harder on execution, though the gap is small.
Pokémon Snap
Timing photos on a moving rail
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.
Pokémon Snap
Creature behavior is fully scripted
Spintires
No opponents
Spintires leans a little harder on variance, though the gap is small.
Pokémon Snap
Minor behavioral wiggle per run
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.
Pokémon Snap
Triggering rare poses is route knowledge
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.
