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
Sitcom puzzle game about rigging perfect prank chains around a fixed routine.

Optimization · Pure Optimization
Designing and optimizing a theme park's layout, pricing, and guest flow to maximize satisfaction and profit.
Neighbours from Hell leans Optimization (Pure Optimization); Planet Coaster 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.
Neighbours from Hell
Timing pranks between patrol windows
Planet Coaster
Precise track and scenery placement rewards manual dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Neighbours from Hell
The neighbour loops a fixed routine
Planet Coaster
No adaptive opponent; guests follow scripted happiness rules
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Neighbours from Hell
Routine unknown on first attempt, then converges
Planet Coaster
Guest mood noise is low and quickly mappable
Planet Coaster leans a little harder on optimization, though the gap is small.
Neighbours from Hell
Sequencing pranks for maximum combo rating
Planet Coaster
Queue routing, pricing, and ride placement are the solvable core
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.
