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
A punishing Soviet off-road logging sim about dragging timber through near-impassable mud.

Optimization · Pure Optimization
On-rails photography game about provoking and capturing the perfect Pokémon shot.
MudRunner leans Optimization (Practiced Mastery); Pokémon Snap leans Optimization (Pure Optimization).
MudRunner leans a little harder on execution, though the gap is small.
MudRunner
Careful throttle, diff-lock and winch control matter constantly.
Pokémon Snap
Timing photos on a moving rail
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
MudRunner
No opponent of any kind.
Pokémon Snap
Creature behavior is fully scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
MudRunner
Deforming mud behaves unpredictably until mapped.
Pokémon Snap
Minor behavioral wiggle per run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
MudRunner
Fuel, load and route planning across the map is the core test.
Pokémon Snap
Triggering rare poses is route knowledge
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.
