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

Optimization · Light / Casual
A point-and-click adventure where inventory puzzle logic is the whole challenge.

Optimization · Pure Optimization
Claymation point-and-click adventure sculpted entirely from plasticine whimsy.
Broken Sword: The Smoking Mirror leans Optimization (Light / Casual); The Neverhood 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.
Broken Sword: The Smoking Mirror
no physical skill, point-and-click
The Neverhood
Point-and-click; no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Broken Sword: The Smoking Mirror
no opponents, puzzle-driven
The Neverhood
No opposition exists
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Broken Sword: The Smoking Mirror
no meaningful randomness
The Neverhood
Puzzles hidden until discovered, then fixed
The Neverhood leans a little harder on optimization, though the gap is small.
Broken Sword: The Smoking Mirror
item puzzle logic is solvable
The Neverhood
Adventure puzzle chains with single 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.
