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

Execution · Practiced Mastery
Foundational ice hockey sim testing stick timing and exploiting goalie angles.

Execution · Pure Mechanics
Island-themed collection of twelve motion-controlled sports showcasing the Wii MotionPlus accessory.
NHL Hockey leans Execution (Practiced Mastery); Wii Sports Resort leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
NHL Hockey
Skating angles, pass timing and shot placement decide goals
Wii Sports Resort
MotionPlus precision in swordplay, archery and bowling
NHL Hockey leans a little harder on reads, though the gap is small.
NHL Hockey
Against a human, baiting checks and goalie reads matter
Wii Sports Resort
Local versus duels involve mild feinting
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
NHL Hockey
Puck bounces add light physical randomness
Wii Sports Resort
Slight physics and CPU pattern randomness
NHL Hockey leans a little harder on optimization, though the gap is small.
NHL Hockey
Exploitable AI angles and line strategy are mappable
Wii Sports Resort
Each event has small learnable technique optima
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.
