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 classic point-and-click adventure where solving inventory puzzles is the entire challenge.

Optimization · Pure Optimization
Claymation point-and-click adventure sculpted entirely from plasticine whimsy.
Grim Fandango Remastered 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.
Grim Fandango Remastered
no physical skill ceiling, 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.
Grim Fandango Remastered
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.
Grim Fandango Remastered
no meaningful randomness
The Neverhood
Puzzles hidden until discovered, then fixed
The Neverhood leans a little harder on optimization, though the gap is small.
Grim Fandango Remastered
item and dialogue puzzle logic 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.
