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

Optimization · Systems & Chaos
A fairy-tale adventure testing patient discovery of fixed puzzle solutions.
Black & White leans Optimization (Pure Optimization); The Night of the Rabbit leans Optimization (Systems & Chaos).
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
The Night of the Rabbit
Pointing and clicking has no motor ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Black & White
Rival gods follow scripted strategies
The Night of the Rabbit
No opponent of any kind to predict
The Night of the Rabbit leans a little harder on variance, though the gap is small.
Black & White
Creature learning quirks surprise first plays
The Night of the Rabbit
Puzzle solutions are hidden information until discovered
Black & White leans a little harder on optimization, though the gap is small.
Black & White
Village economy, belief spread, and creature training
The Night of the Rabbit
A walkthrough trivialises it - puzzles have fixed solutions
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.
