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
Designing and optimizing a theme park's layout, pricing, and guest flow to maximize satisfaction and profit.

Optimization · Pure Optimization
A park management puzzle where understanding the guest happiness formula lets you solve each scenario optimally.
Planet Coaster leans Optimization (Pure Optimization); RollerCoaster Tycoon 2 leans Optimization (Pure Optimization).
Planet Coaster leans a little harder on execution, though the gap is small.
Planet Coaster
Precise track and scenery placement rewards manual dexterity
RollerCoaster Tycoon 2
Track building is grid-based with modest placement precision demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Planet Coaster
No adaptive opponent; guests follow scripted happiness rules
RollerCoaster Tycoon 2
Guest behaviour follows fixed preference scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Planet Coaster
Guest mood noise is low and quickly mappable
RollerCoaster Tycoon 2
Very little randomness once ride stats are understood
RollerCoaster Tycoon 2 leans a little harder on optimization, though the gap is small.
Planet Coaster
Queue routing, pricing, and ride placement are the solvable core
RollerCoaster Tycoon 2
Pricing, ride stats, and park layout are near-perfectly 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.
