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
Open-city checkpoint racing testing arcade car control and route knowledge.

Execution · Pure Mechanics
Island-themed collection of twelve motion-controlled sports showcasing the Wii MotionPlus accessory.
Midtown Madness 3 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.
Midtown Madness 3
Arcade car control through traffic is the core demand
Wii Sports Resort
MotionPlus precision in swordplay, archery and bowling
Wii Sports Resort leans a little harder on reads, though the gap is small.
Midtown Madness 3
AI racers follow scripted lines
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.
Midtown Madness 3
Live traffic adds mild run-to-run noise
Wii Sports Resort
Slight physics and CPU pattern randomness
Midtown Madness 3 leans a little harder on optimization, though the gap is small.
Midtown Madness 3
City shortcut knowledge wins checkpoint races
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.
