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 knowledge-based mystery solved by mapping a deterministic solar system.

Optimization · Pure Optimization
The beloved theme park builder where you design coasters and manage every detail of a growing park.
Outer Wilds leans Optimization (Pure Optimization); RollerCoaster Tycoon leans Optimization (Pure Optimization).
Outer Wilds leans a little harder on execution, though the gap is small.
Outer Wilds
Light piloting, mostly forgiving
RollerCoaster Tycoon
Mouse-driven building with no time pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Outer Wilds
World is fixed; nothing adapts to you
RollerCoaster Tycoon
Guests are simple, fully mappable simulations
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Outer Wilds
Loop is deterministic once understood
RollerCoaster Tycoon
Guest spawns and breakdowns barely matter
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Outer Wilds
Pure knowledge puzzle - solve the system
RollerCoaster Tycoon
Park layout, pricing, and coaster stats 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.
