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 blending city building, creature training and conquering by awe or force.

Optimization · Pure Optimization
Engineering structurally sound brick builds under physical constraints.
Black & White 2 leans Optimization (Pure Optimization); LEGO Bricktales 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 2
Gesture casting and creature handling need mild dexterity.
LEGO Bricktales
Placing bricks needs care, not speed
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Black & White 2
Creature learning is trainable, not adversarially adaptive.
LEGO Bricktales
No opponent in a diorama
Black & White 2 leans a little harder on variance, though the gap is small.
Black & White 2
Creature behaviour quirks add some unpredictability.
LEGO Bricktales
Puzzles are fixed once seen
Black & White 2 leans a little harder on optimization, though the gap is small.
Black & White 2
City impressiveness versus army economy is the solvable choice.
LEGO Bricktales
Engineering stable builds within constraints is the test
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.
