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 · Light / Casual
A branching visual novel testing only route mapping across fixed story paths.

Optimization · Pure Optimization
A time-travel mystery where finding the correct sequence of phone interventions is the puzzle.
Psycho-Pass: Mandatory Happiness leans Optimization (Light / Casual); Steins;Gate 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.
Psycho-Pass: Mandatory Happiness
Reading text requires no inputs of consequence
Steins;Gate
Pure reading; phone choices are the only input
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Psycho-Pass: Mandatory Happiness
Scripted branching characters cannot adapt
Steins;Gate
No opponent; timeline branches are fixed
Psycho-Pass: Mandatory Happiness leans a little harder on variance, though the gap is small.
Psycho-Pass: Mandatory Happiness
Branch outcomes are hidden until a route is explored
Steins;Gate
Phone trigger timing hides branch conditions until discovered
Steins;Gate leans a little harder on optimization, though the gap is small.
Psycho-Pass: Mandatory Happiness
Mapping choice trees to endings is light solvable work
Steins;Gate
Mapping exact phone responses to unlock the True End is solvable
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.
