head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Optimization · Practiced Mastery
Zelda-flavored musou about juggling battlefield objectives while mowing hordes.

Optimization · Practiced Mastery
A punishing Soviet off-road logging sim about dragging timber through near-impassable mud.
Hyrule Warriors leans Optimization (Practiced Mastery); MudRunner leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Hyrule Warriors
Combo strings and weak-point gauge timing
MudRunner
Careful throttle, diff-lock and winch control matter constantly.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Hyrule Warriors
Enemy hordes are mindless and scripted
MudRunner
No opponent of any kind.
MudRunner leans a little harder on variance, though the gap is small.
Hyrule Warriors
Minor drop and mission randomness
MudRunner
Deforming mud behaves unpredictably until mapped.
MudRunner leans a little harder on optimization, though the gap is small.
Hyrule Warriors
Keep management, character builds, and map priorities
MudRunner
Fuel, load and route planning across the map is the core test.
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.
