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.

Optimization · Systems & Chaos
Medieval dynasty sim with chaotic event-driven stories.

Optimization · Pure Optimization
Turn-based team-building optimization with collection RNG and optional human battles.
Crusader Kings II leans Optimization (Systems & Chaos); Pokémon Ultra Moon leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Crusader Kings II
pausable, no reflex
Pokémon Ultra Moon
Turn-based menus require no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Crusader Kings II
AI characters scripted not adaptive
Pokémon Ultra Moon
Only human link battles involve predicting switches
Crusader Kings II leans a little harder on variance, though the gap is small.
Crusader Kings II
dynastic events, traits, intrigue
Pokémon Ultra Moon
Wild encounters, IVs and catch rolls add randomness
Pokémon Ultra Moon leans a little harder on optimization, though the gap is small.
Crusader Kings II
succession, marriages, claims plannable
Pokémon Ultra Moon
Type matchups and team building are the solvable core
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.
