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
A kart racer where controlled chaos from random items tempers otherwise precise driving skill.

Execution · Twitch Chaos
Procedural room-clearing where randomised suspects punish sloppy doctrine and slow aim.
Mario Kart 8 leans Execution (Twitch Chaos); Police Stories leans Execution (Twitch Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Mario Kart 8
precise drifting and item timing matter
Police Stories
Snap aim and door-breach timing decide split-second encounters
Mario Kart 8 leans a little harder on reads, though the gap is small.
Mario Kart 8
minimal, mostly reacting not predicting
Police Stories
Suspect AI is randomised, not adaptively modelling you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mario Kart 8
item boxes are heavily randomized
Police Stories
Suspect placement and compliance rolls differ every attempt
Police Stories leans a little harder on optimization, though the gap is small.
Mario Kart 8
track lines and item strategy solvable
Police Stories
Room-clearing procedure and tool usage converge to doctrine
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.
