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 · Pure Mechanics
Arcade racing with Mario Kart-style power-ups bolted onto licensed cars.

Execution · Pure Mechanics
An arcade maze shooter where players blast monsters and, occasionally, each other.
Blur leans Execution (Pure Mechanics); 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.
Blur
Racing lines and dodging shots demand car control
Wizard of Wor
Quick corridor shootouts reward reaction speed
Blur leans a little harder on reads, though the gap is small.
Blur
Human racers bait and time power-ups against you
Wizard of Wor
Two-player mode lets partners turn on each other
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Blur
Power-up pickups and incoming attacks add chaos
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.
Blur
Track knowledge and pickup routes are learnable
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.
