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 · Twitch Chaos
GameCube kart racer with two riders per kart trading items mid-drift.

Execution · Pure Mechanics
An arcade maze shooter where players blast monsters and, occasionally, each other.
Mario Kart: Double Dash!! leans Execution (Twitch Chaos); Wizard of Wor 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.
Mario Kart: Double Dash!!
Two-character swaps and drift timing
Wizard of Wor
Quick corridor shootouts reward reaction speed
Mario Kart: Double Dash!! leans a little harder on reads, though the gap is small.
Mario Kart: Double Dash!!
Item duels against humans reward baiting
Wizard of Wor
Two-player mode lets partners turn on each other
Mario Kart: Double Dash!! leans a little harder on variance, though the gap is small.
Mario Kart: Double Dash!!
Special item rolls swing races
Wizard of Wor
Invisible monsters and the warping Worluk hide information
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Mario Kart: Double Dash!!
Character pairings and lines are solved
Wizard of Wor
Maze control strategies converge with play
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.
