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.

Optimization · Pure Optimization
God game about winning worshippers through miracles and training a giant pet creature.

Optimization · Pure Optimization
Team building and type-matchup optimization through a scripted island campaign.
Black & White leans Optimization (Pure Optimization); Pokémon 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.
Black & White
Gesture-cast miracles; minimal dexterity stakes
Pokémon Moon
Turn-based menus require no dexterity
Pokémon Moon leans a little harder on reads, though the gap is small.
Black & White
Rival gods follow scripted strategies
Pokémon Moon
Scripted trials and trainers; competitive play is a niche mode
Pokémon Moon leans a little harder on variance, though the gap is small.
Black & White
Creature learning quirks surprise first plays
Pokémon Moon
Encounter tables, catch rolls and crits are mappable RNG
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Black & White
Village economy, belief spread, and creature training
Pokémon Moon
Team composition and type math 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.
