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
Souls-flavored melee timing through randomized dungeon floors.
Mario Kart 8 leans Execution (Twitch Chaos); Necropolis 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
Necropolis
Stamina-based melee timing carries every encounter
Mario Kart 8 leans a little harder on reads, though the gap is small.
Mario Kart 8
minimal, mostly reacting not predicting
Necropolis
Monsters follow fixed behaviors, never adapting
Mario Kart 8 leans a little harder on variance, though the gap is small.
Mario Kart 8
item boxes are heavily randomized
Necropolis
Procedural floors and item rolls reshape each run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Mario Kart 8
track lines and item strategy solvable
Necropolis
Item knowledge and codex unlocks reward system mapping
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.
