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 comic-panel puzzle game where you arrange characters and events to produce a specified story outcome.

Optimization · Pure Optimization
A classic management sim about building profitable, animal-friendly zoo exhibits.
Storyteller leans Optimization (Pure Optimization); Zoo Tycoon leans Optimization (Pure Optimization).
Storyteller leans a little harder on execution, though the gap is small.
Storyteller
Dragging characters into comic panels needs no dexterity
Zoo Tycoon
Mouse-driven building, no time pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Storyteller
No opponent; narrative puzzle arrangement
Zoo Tycoon
No opponents
Zoo Tycoon leans a little harder on variance, though the gap is small.
Storyteller
Story logic is deterministic
Zoo Tycoon
Animal needs are deterministic once learned
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Storyteller
Arranging characters and props into the exact causal sequence that satisfies each title
Zoo Tycoon
Exhibit suitability, finances, guest flow are solvable systems
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.
