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

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

Execution · Pure Mechanics
The first online Mario Kart, infamous for the execution-heavy snaking technique dominating play.
Blur leans Execution (Pure Mechanics); Mario Kart DS leans Execution (Pure Mechanics).
Mario Kart DS leans a little harder on execution, though the gap is small.
Blur
Racing lines and dodging shots demand car control
Mario Kart DS
Snaking demands relentless precise drift inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Blur
Human racers bait and time power-ups against you
Mario Kart DS
Online opponents punish predictable lines
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
Mario Kart DS
Item RNG decides tight finishes
Mario Kart DS leans a little harder on optimization, though the gap is small.
Blur
Track knowledge and pickup routes are learnable
Mario Kart DS
Kart stats, lines, and snaking routes
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.
