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 · Pure Optimization
The beloved theme park builder where you design coasters and manage every detail of a growing park.

Optimization · Pure Optimization
A first-person factory builder that is pure logistics optimization.
RollerCoaster Tycoon leans Optimization (Pure Optimization); Satisfactory 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.
RollerCoaster Tycoon
Mouse-driven building with no time pressure
Satisfactory
Light platforming, no real mechanical ceiling.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
RollerCoaster Tycoon
Guests are simple, fully mappable simulations
Satisfactory
No adaptive opponent in the world.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
RollerCoaster Tycoon
Guest spawns and breakdowns barely matter
Satisfactory
Resource nodes are fixed once mapped.
Satisfactory leans a little harder on optimization, though the gap is small.
RollerCoaster Tycoon
Park layout, pricing, and coaster stats are solvable systems
Satisfactory
Ratios, logistics, and factory layout are everything.
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.
