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

Execution · Twitch Chaos
Souls-flavored melee timing through randomized dungeon floors.

Execution · Twitch Chaos
Flipper execution and table knowledge with Pokémon-catching RNG on top.
Necropolis leans Execution (Twitch Chaos); Pokémon Pinball 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.
Necropolis
Stamina-based melee timing carries every encounter
Pokémon Pinball
Flipper timing and nudge control are the whole input
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Necropolis
Monsters follow fixed behaviors, never adapting
Pokémon Pinball
A pinball table has no mind
Necropolis leans a little harder on variance, though the gap is small.
Necropolis
Procedural floors and item rolls reshape each run
Pokémon Pinball
Ball physics and catch-mode rolls add real randomness
Necropolis leans a little harder on optimization, though the gap is small.
Necropolis
Item knowledge and codex unlocks reward system mapping
Pokémon Pinball
Mode routing and table knowledge raise scores predictably
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.
