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

Optimization · Pure Optimization
A time-travel mystery where finding the correct sequence of phone interventions is the puzzle.

Optimization · Pure Optimization
Claymation point-and-click adventure sculpted entirely from plasticine whimsy.
Steins;Gate leans Optimization (Pure Optimization); The Neverhood leans Optimization (Pure Optimization).
The Neverhood leans a little harder on execution, though the gap is small.
Steins;Gate
Pure reading; phone choices are the only input
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.
Steins;Gate
No opponent; timeline branches are fixed
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.
Steins;Gate
Phone trigger timing hides branch conditions until discovered
The Neverhood
Puzzles hidden until discovered, then fixed
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Steins;Gate
Mapping exact phone responses to unlock the True End 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.
